Introduction Getting Older is Not for Sissies
When it comes to aging, life can be cruel. There’s plenty to...well...let’s come
right out and say it: think about. What will happen to my looks? What will
happen to my body? Will I still be able to pursue my interests? How will I
manage financially? What will happen to my mind?
That last question is now the second leading health concern (after cancer).
Fear of developing dementia would likely stir even more concern if many
people didn’t mistakenly believe a cure exists (more than 45 percent of
surveyed respondents think there is an effective treatment).
It comes down to this: Choices we make throughout life about how much or
how little physical activity we do, and what we put in our bodies protects
against dementia or shunts us towards it.
If you feel you are losing your memory, finding it hard to focus or concentrate,
have difficulty in learning or taking in new information, experience brain
fog, often feel flustered and scattered, have lost your zest and “get up and
go” motivation for life and living your brain may be growing old too fast or
degenerating.

These are signs and symptoms of brain degeneration and if these things
are happening to you it is NOT a normal part of aging.
The good news is the brain is extremely adaptable and wants to get well.
You simply have to know how to feed and care for your brain.
Brain degeneration affects millions of people of all ages all over the world.
The destruction sets in years or even decades before serious neurological
diseases like dementia, Alzheimer’s, Parkinson’s, multiple sclerosis, or other
serious life- shattering conditions can be diagnosed.
You will find it exciting to discover exactly what you can and should do
about protecting your brain function for the long haul with strategies using
simple exercise, diet and lifestyle changes that can profoundly impact your
brain health and thus the quality of your life.

How Our Lives
Have Changed
Our world has changed a great deal in the last century and just less than
100 years ago a hardworking man would spend his day sweating behind a
horse and plough. If he wanted to go to the village he would cycle and in the
evenings he would do home repairs. His wife would be doing all the housework
without appliances and cooking from scratch without a microwave.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 5
It is an exciting time to be alive
in human evolution but there is a
dark side to the comfort and ease
of our modern conveniences. It
has also contributed to sedentary
and inactive life-styles becoming
the norm in large segments of the
population.
It’s true, many of us spend our days hardly moving. We go from our bed, to
sit in our car, to our desk where we sit all day. The most physical work we
do is to click a mouse as we sit motionless in front of a computer screen.
We get back in our car for the drive home only to sit in front of a screen of
some sort remaining virtually motionless till we go to bed again.
Up to 80 percent of the
day is spent sitting in one
type of chair or another.
This means nearly all of the
16 odd hours we are awake
is spent in a sedentary
manner expending very
little energy.
The most direct effect of sitting idle is that the work performed by the
large skeletal muscles in the legs, back, and trunk required for upright
movement comes to a halt.
Over the time course of just one day this causes the loss of opportunity for
cumulative energy expenditure (calories burnt) resulting from thousands
of intermittent muscular contractions throughout the 16 hour period
that people are awake. This is where the propensity to become unhealthy,
overweight and sick originates from.
Unaware of the danger, we carry on living our modern day inactive life
but we are paying a very high price for it. The chronic “lifestyle” diseases
killing us in increasing numbers take ten, twenty or more years to manifest
themselves and when they do show there is not a pill or medical procedure
that can fix them.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 7
The frightening fact is that already fifty percent of the world’s population
has a chronic “lifestyle disease” and many have multiple conditions which
slowly siphon their lives away. These diseases such as heart disease, cancer
and diabetes and dozens (hundreds) of others are called “lifestyle diseases”
because they are caused by the way we live our lives. Caused by what we
do and don’t do every single day in the way of proper exercise and proper
nutrition and other healthy lifestyle habits.
So I ask you to forgive me if at times I seem harsh or too intense as it’s because
of the passion I have for at least informing people of the situation. Then they
can make their own choices and my job is done and I am a happy woman.
Then I can only hope you make the right decisions going forward.
Now let’s drill down into how lack of physical activity impacts the human
body and brain.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 8
Chapter One
Why Strength Matters
Why Strength Matters
Physical strength has always been the most important thing in a human
beings life. This is true whether we want it to be or not. As humanity has
advanced throughout history, physical strength has become less critical to
our daily existence, but no less important to our lives.
Our strength, more than any other attribute we possess still determines
the quality and the quantity of our life. Whereas previously our physical
strength determined if we were eaten by other animals or our enemies,
how much food we ate, how warm and dry we stayed, and our capabilities
to raise our young, it now merely determines how well we function in the
new modern surroundings we have crafted for ourselves as our culture
has evolved.
As the nature of that culture has changed, our relationship with physical
activity has changed along with it. We previously were physically strong as
a function of our continued existence in a simple physical world. We were
adapted to this existence well, since we had no other choice. We do have a
choice now but the basic blueprint remains with us.
Since most of us now have been freed from the necessity of personally
obtaining our subsistence, physical activity is regarded as optional. It may
be from the standpoint of immediate necessity, but the reality of millions
of years of adaptation to an existence will not just go away because desks
and cars were invented.
Our bodies have not changed in tens of thousands of years. They were
designed to be active – very active. They are designed for hard physical
work which is the necessary signals that tell our body that its strength is
needed to feed a family. That it is needed to remain alive and well.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 10
Early man had all the activity needed built into their daily lives so there was
no need to add extra in. Today it is very different, we do not use our muscles
in daily life as all of the “grunt work” has been replaced by technology or
machinery which although makes our lives “easier” it also robs us of the
physical activity a human body and brain needs to remain healthy and
disease free.
This is the same genetic blueprint we have had since man appeared on this
earth. Resources were scarce and our DNA was based on that fact and has
not changed or had time to adapt to our modern sedentary world.
We used to think the difficulties with getting older was simply due to the
number of candles on our birthday cake but with ongoing research we now
know this is from nothing more than disuse.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 11
To boil it down, if we continue to send
signals to the brain that strength is needed
the body will assume there is a family that
needs feeding and protecting and to ensure
survival of the species the “shutdown mode”
switch is not activated. It is that basic.
The body and brain does not know how old it is it only knows the chemical
instructions it is receiving that either tell the body to repair, replace, renew,
and rejuvenate old worn out cells and tissues or the opposite happens -
chemicals whisper to the cells – Degenerate. Decay. Die.
This is what we are seeing all around us, in our families and communities as
the disease rate is skyrocketing taking out people long before their time.
Now would be a
good time to ask
yourself what
signals are you
sending your
body and brain?
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 12
Somehow people do not know or believe how crucial it really is and do not
understand how important their body’s muscular system and its condition
are to the state of their overall health.
The reality is this syphoning of strength is unseen. Often body weight can
remain the same as fat creeps into the space left by the shrinking muscle
tissue so there is little to no outer evidence of this happening.
Most people are simply not aware that it is our healthy toned muscle tissue
serves as body’s armour and defence system against killer diseases and
illness and a human body without enough muscle building and maintaining
activity can lose up to 50 percent of muscle mass by the age of 70 years.
We can either begin the long process of becoming weaker or we can work
to maintain our strength for the rest of our life.
After this point, if the body does not receive the necessary stimulus to
trigger muscle growth, a slow process of muscle wasting begins. This loss
of muscle tissue hastens the degenerative processes and conditions that
characterize the dreaded aging process.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 13

Diminished
muscle
muscles
development
All body systems weaken including the brain and the immune system
leaving one exposed to life threatening dementia and disease. This is
serious as research shows even a 1 percent loss in lean body mass (LBM)
means impaired immune function.
You will not hear about this very often but it is the central cause of the
epidemic of current lifestyle disease. It’s a fact; modern medicine does
not concern itself with lifestyle problems. Doctors don’t treat them and
medical training does not teach one how to rebuild a weakened human
body and brain.
This is where proper exercise comes in as studies are showing that regular
strength training exercise provides long-term brain health and immune
protection, it causes adaptations that allow the body to withstand training
stress and recover from it more efficiently.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 14
In effect, you are building a protective shield in the body and brain
against disease. The up-regulation of energy use and protein synthesis
with a minimal stress hormone response shows how strength training
improves more than just body composition, muscle force and mobility.
It makes the body and brain work better to repair tissue and fight off
disease and dementia.
This is where you get the massive reduction in disease risk - up to 80 percent
in fact - from this one simple lifestyle strategy amounting to 2-3 total hours
each week dedicated to maintaining your body structures [1]
This makes sense as the human body is a “use it or lose it” machine as we
have previously discussed.
You see, your muscles do far more than just make movement possible.
There is now clear evidence that the muscles that make up to 50 percent
of our body weight also play an important role in metabolic and brain
health and wellness.
Now-a-days, we hardly ever have to bend down, lift and carry, reach, twist,
climb, stretch or run. When we finally get up out of our chair and attempt to
use our body, pain and even injury can be the outcome. We are engineered
for a lifestyle we no longer live.
Although the message is getting out there about the crucial need for
proper exercise people seem to be in denial of its importance in our lives.
Even with modern medicine finding cures for many diseases and illnesses
our health has been steadily declining since World War II. For example in
the last four decades the prevalence of overweight adults has increased
from 31 percent to 64 percent alone.
We absolutely know now, that the main reason for this decline in health
is our steady loss of muscle mass as we have become more sedentary. Up
until recently the scientific and medical communities have taken muscle
strength and mass for granted. The loss of muscle throughout adult life
didn’t even have a name until 1988.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 15
The term “sarcopenia” that is used to indicate the progressive reduction in
muscle mass and muscle strength is strongly associated with bone loss and
osteoporosis. The two go together hand in hand.
All of the attention has been given to osteoporosis. Yet our muscles are
attached to bone and if muscles are not kept strong there is less pulling on
the bones they are attached to so they weaken as well.
Millions of people have sarcopenia - both YOUNG and old, and the condition
is predicted to become one of the biggest health problems the world faces.
It is suddenly a very hot topic in aging research as it has a devastating effect
on the quality of the last 20 -30 years of a person’s life.
Many people believe they are active enough because they are “busy” and
are often rushing around. But being busy does not work the major muscle
groups through their ranges of movement under an adequate load which is
the formula for muscle building and maintaining activity.
There in no way you would get that sort of muscle stimulating activity from
the normal tasks and activities of everyday life - unless you happen to have
a job as a manual labourer, which is not so common these days.
For the human body, food was scarce for the majority of the time over
which it evolved. As a result, the human body is tremendously efficient at
converting body tissue into life-sustaining energy - so anything not being
used weakens and withers.
Unused muscles weaken and shrink and unloaded bones lose density,
thickness and strength. Unused brain neurons die and nerves not being
used degenerate.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 16
Unused joints and tendons lose strength and get damaged easier. An
unused heart becomes scrawny and weak and cannot pump effectively.
Lung capacity diminishes, and the red blood cell count declines if oxygen
demand is low.
All of this means that there is a high price to pay for not getting enough
proper exercise. Physical inactivity adversely affects the function of the
muscles, bones, brain, heart, blood vessels, liver, the immune system and
every other organ and system in the human body.
An inactive person is more likely to suffer from anxiety and depression, find
stress harder to manage, and lose self-confidence and self-esteem.
Not being active affects the body right down to the cellular level where
the ability to transfer oxygen and nutrients from the bloodstream to cells
is diminished. And if you can’t get enough oxygen out of your blood the
quality of your entire life is affected and your body attracts disease rather
than repels it.
Without enough activity dangerous fat builds up inside our bodies when
fat burning enzymes cannot do their job properly when blood circulation
is slowed down in the low energy environment already mentioned earlier.
This fat wraps itself around major organs and releases toxic chemicals in
the most susceptible part of the human body –the abdomen where all of
our working “machinery” is located.
You can be at normal body weight and have this harmful fat deep inside
your body and you will not even know that you have it. But if you do not
do enough physical activity you will likely have it and it sets the stage for
massive health risks.
It’s such a simple concept… activity that works our muscular system forces
our body and brain to grow. Sitting around and living a no-exercise lifestyle
encourages the body and brain to decay, AND, you must keep reminding
your body and brain over and over that its strength and efficiency is needed
right throughout adult life.

It may be time to ditch the desk chair: A new study links sitting too much
each day with memory problems in adults.
The new study linked sedentary behavior to thinning of the medial temporal
lobe, a brain region involved in the formation of new memories and this
thinning can be a precursor to cognitive decline and dementia.
The participants in the study reported that they spent from 3 to 7 hours,
on average, sitting per day. With every hour of sitting each day, there was
an observed decrease in brain thickness, according to the study.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 18
I think you’ll agree this is serious stuff but don’t you worry as I have developed
a simple exercise program you can do easily at home with minimal equipment
that you will receive when you get started on the “Ageless Brain” program.
If you are sitting too much now, taking a short break of just 10 minutes to
do this easy program will help balance the sitting you may be doing.
It is true that our pursuit of comfort has produced a world in which we can
remain almost entirely motionless. You can pull up to the grocery store, and
they will load up your groceries for you. If that’s too much work, Amazon
will deliver groceries to your front door.
If you lay down on the couch and don’t want to reach across and grab the
remote, no sweat! “Hey, Google! Play War of the Worlds.” Its possible Google
drones will be delivering our hamburger and chips to us soon. We are told
that this is the good life: seated, entertained, and having technology take
care of every need.
Physical strength and fitness remains not only useful in the 21st century,
but of critical importance. It is the last reliable means to promote the
physical movement that increases the length and quality of life, increases
cognitive potential, and improves emotional state.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 19
Your
health
depends on
movement
The body contributes far more to our lives than just physical attributes such
as strength and endurance - it plays a major role in emotions, learning and
relationships. The body is intimately involved in all our thought processes,
understanding, emotions and decision making. The mind and body are
inseparable, from our endocrine system to the “brain in our gut” - the body
is your brain!
Being sedentary has become “normal”. A modern human has the luxury to
ask why run? Why jump? Why climb? Why lift? Why carry? When everything
is accessible, when you are not forced to move to catch your prey or avoid
being prey.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 20
Most people have a disconnect between their mind and body. We work in
jobs that don’t require our bodies, simply sitting at desks clicking a mouse
and tapping on keyboards. The narrative and relationship between our
bodies and our movement is forgotten, not heard, ignored. We only notice
our bodies when “something goes wrong” with it.
Without a good measure of strength and fitness, you are quite simply not as
useful as you would be with it. It is a primary priority because it magnifies
our efforts in every other area of our life.
This should be enough to justify fitness and health as the foundation of our
society and our schools, but there is still so much more reason to get strong
and fit in the modern world to prevent the near-epidemic proportion of
body and brain decline in adults of all ages.

Chapter Two
Don’t Lose Your Marbles
Staying Sharp So Your Health Span
Matches Your Life Span
Fifty years ago it was believed that aging bought with it a loss of brain
function, of memory and mental agility and that once neurons die, nothing
could be done about it. Hence deterioration and progressive memory
decline was considered a more or less inevitable part of aging.
Its already well known that leading a sedentary life is detrimental to long-
term health and puts a person at higher risk for chronic conditions such as
heart disease, diabetes and cancer or any one of dozens of other “lifestyle”
related conditions. But research shows that spending more time on the
couch and less time being active is also a fast-track to cognitive decline. It
turns out lack of enough proper exercise leads to a decrease in brain size.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 23
Dementia is at epidemic disease proportions - affecting one in eight
people aged 65 and over who are living with the disease. In the next 20
years, it is estimated that dementia will affect one in four rivalling the
current prevalence of obesity and diabetes.
Globally, the numbers of people living with dementia will increase from
46.8m in 2015 to 131.5m in 2050, a 281 percent increase.
There is still no known accepted cure for this devastating disease, and no
effective medical treatments. Dementia drugs are often of little to no
benefit at all, which underscores the importance of prevention throughout
your lifetime.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 24
Poor Fitness Now = Smaller Brain Later
We’ve all come to accept the notion that our brain will shrink as we get more
candles on our birthday cake. And nowhere in the brain is this decline more
impactful than in the hippocampus, the memory center, one of the primary
brain areas that’s first to decline in dementia or Alzheimer’s disease.
However, new and exciting research challenges the notion that this is just
a natural part of the aging process and shows that we have the potential
to actually grow new cells in this vitally important area of the brain. We can
actually expand the hippocampus in size and enhance memory function.
A curved structure nestled deep within the brain, the hippocampus (from greek word
for sea horse) plays a major role in forming, storing and processing memories.

However, new and exciting research challenges the notion that this is just a
natural part of the aging process and shows that we have the potential to
actually grow new cells in this vitally important area of the brain. We can
actually expand the hippocampus in size and enhance memory function.
Scientists have linked physical exercise to brain health for many years.
In fact, there’s compelling evidence that physical exercise helps build a
brain that not only resists shrinkage, but increases cognitive abilities by
promoting neurogenesis, i.e. your brain’s ability to adapt and grow new
brain cells.
Exercise helps protect and improve your brain function by improving and
increasing blood flow to your brain; increasing production of nerve-protecting
compounds; improving development and survival of neurons; and reducing
damaging plaques in your brain. Over time, the cumulative effects help slow
down the rate at which your brain ages.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 26
“Brain volume is one marker of brain aging. Our brains shrink as we age, and
this atrophy is related to cognitive decline and increased risk for dementia,”
says lead author Nicole Spartano, a trainee at the Whitaker Cardiovascular
Institute at Boston University School of Medicine. “So it is important to
determine the factors - especially modifiable factors, such as poor fitness -
that contribute to brain aging.”
It’s among the first studies to actually put a number on how beneficial
exercise can be for the brain. The researchers asked a group of 1,228 men
and women of diverse racial and ethnic backgrounds living in Manhattan
about their regular exercise habits. They also answered questions that
tested their cognitive abilities, including their memory, organization,
reasoning and thinking speed. Five years later, they performed the same
tests on about half of the study group.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 27
People who reported doing more physical activity showed higher scores on
cognitive tests - consistent with previous studies linking more exercise to
better brain health. But when the researchers adjusted for the effect that
factors like high blood pressure, diabetes and heart disease can have on
brain function, the link disappeared.
Conditions like these could impair blood flow to the brain and therefore
compromise cognitive functions, says Dr Clinton Wright, associate professor
of neurology and public health sciences at University of Miami and senior
author of the study. “That suggests that people with low physical activity
levels also had a greater burden of those risk factors,” he says.
He and his colleagues then focused just on people in the study who didn’t
have these blood flow risk factors, and compared their cognitive scores
at the beginning and end of the study. They found similar trends showing
that people who exercise more had higher cognitive scores, while those
who were less physically active tended to have lower scores. This time, even
after accounting for the contribution of possible confounding factors, they
found that this trend remained strong in two areas in particular: thinking
speed and memory of specific past events.
They also found that people who exercised less showed sharper declines in
their cognitive scores than people who were more active. The drops were
equivalent to the declines found during normal aging over about 10 years,
they concluded.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 28
How Exercise Protects
and Improves Brain Function
When you challenge your muscles with challenging physical activity it
increases blood flow to your brain elevating oxygen levels. This triggers
bio-chemical (hormonal) changes that result in new neurons being formed
that are then bathed and protected with a released nerve growth factor
called brain-derived neurotropic factor (BDNF).
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 29
You can increase your BDNF levels and enhance the growth of new brain cells
and memory. Just like your muscles, your brain cells need to be stressed to
grow and this is where a structured exercise program comes in.
An adult neuron
is capable of
reorganizing its
neural network
by forming new
connections.
Similarly, a year-long human study [5] found that adults aged 55-80 who
exercised regularly by walking briskly for up to 40 minutes 3 times a week
enlarged their brain’s memory center (anterior hippocampus) 1 to 2 percent
per year, where typically the hippocampus tends to shrink in later years by
1.4 percent per year without enough physical activity.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 30
While the benefits of a strengthening workout have been well-known for
below-the-neck for a long time, the incredible advantages for your brain
are just being discovered.
Research is showing
that physical exercise
improves mood, memory, attention, creativity, and learning and reduces
depression, age-related decline, and the risk of dementia. A recent Finnish
study [6] with twins showed exercise to reduce dementia risks even over
genetics.
Even babies of mothers who exercised during pregnancy are born with
more mature brains.
So much evidence is
accumulating that
physical exercise is
the miracle potion for
getting and keeping
your brain healthy at
any age.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 31
Exercise Also Promotes
Psychological Health and Good Mood
Memory and cognition are not the only benefits associated with physical
fitness. Exercise is also known to dispel depression - in many cases more
effectively than antidepressants.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 32
Creativity also gets a boost from physical activity. According to Stanford
University researchers, a workout session can increase creativity by up to
60 percent.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 33
Then, in addition to a well-rounded workout routine, I also recommend as
much incidental daily activity you can do along with standing up as much
as possible throughout the day to avoid the well-documented hazards
associated with chronic sitting.
Another study [9] involved 86 women between the ages of 70 and 80 who
also had MCI. The women were divided into 3 groups: 1) a resistance training
group, 2) an aerobic exercise group, and 3) a balance and tone training
group. Each group exercised twice a week for six months.
This study is one of the first randomized controlled trials comparing the
efficacy of both resistance and aerobic training to improve cognitive
functions.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 34
It confirms the results obtained a few years ago by the same team of
researchers showing that 12 months of once-or twice-weekly strength
training improved executive functions in healthy women ages 65- to 75
years old for up to 1 year after the training.
The novelty of the study is to show that after a short period of time (6
months) the effects of strength training can benefit cognition, even in
people who are already suffering from cognitive impairment. Just 20
minutes of strength training was found to enhance long-term memory by
about 10 percent.
Research has also shown that burning of the equivalent of 350 calories
three times a week through sustained, sweat-inducing activity can reduce
symptoms of depression as effectively as antidepressants and with none of
the side effects.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 35
Exercise helps protect and improve your
brain function by:
• Improving and increasing blood flow to your brain
• Increasing production of nerve-protecting compounds
• Improving development and survival of neurons
• Reducing damaging plaques in your brain
• Altering the way these damaging proteins reside inside
your brain, which appears to slow the development of
dementia.

Keep Up Your Physical Activity
From 40 years and onwards, physical movement becomes really paramount,
so this is not the time to fall prey to the couch. The act of avoiding exercise
doesn’t kill brain cells, however, the effects that are associated with lack of
exercise happen to be killers.
Proper exercise reduces stress levels, chance of brain damage, and even
creates new brain cells. If you are avoiding exercise, you happen to be
setting your brain cells up for an early death.
Plenty of research confirms that even if you start exercising at this time,
you stand to gain a great deal. It’s really never too late to begin. And…
perhaps just as important as a regular structured proper exercise program,
is to simply move around a lot and avoid sitting as much as possible.
While it’s never too late to start exercising, the earlier you begin and the
more consistent you are, the greater your long-term rewards. Having an
active lifestyle is really an investment in your future well-being, both
physically and mentally.
The science is really clear on this point: memory loss and cognitive decline
really depends on your lifestyle. Your brain has the capacity to regenerate
and grow throughout your entire life, from cradle to grave, and movement
is a major key for all of these brain-boosting processes to occur.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 37
This study followed 324 female twins, aged 43 to 73, for a decade. Cognitive
function such as learning and memory was tested at the outset and at the
conclusion of the study. Interestingly, as reported by MedicineNet.com:
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 38
Your brain’s hippocampus, i.e. your memory
centre, is particularly adaptable and capable
of releasing hormones from the muscles and
growing new cells throughout your entire
lifetime, even into your 90s, provided your
lifestyle supports it.
A meta-analysis of more than a dozen related studies [12] that looked at the
effect of physical activity on the development of brain illnesses found that
exercise reduces the risk of dementia and Alzheimer’s disease by 28 percent
and 45 percent respectively. The evidence also strongly supports the idea
that physical activity prevent age-related cognitive decline.
When you partake in proper exercise, you think better, concentrate better,
and your memory will be better. It boosts blood flow and growth factors in
the brain so you can keep your marbles no matter how long you live.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 39
It’s time to stop thinking that fitness stops at the neck and remember that
our brain is the central processing unit for all of the body’s systems and
processes. Its health is very important.
The exact same “Use it or lose it” concept that applies to our physical body
also applies to our brain. The brain, just like a muscle in our body, can weaken
and wither if we don’t use it.
When you improve and strengthen physical health you improve and
strengthen mental health too. With our modern world moving so fast with
computers, faxes, cell phones and other technology people are expected
to multitask and work at a fast pace. We get used to moving quicker and
constantly ‘doing’ and we forget that we also need down time to de-stress
and purge the busyness of our lives from our entire body.
The effects of our busy lives can affect people in many ways and one of
them is the fact that many people are plagued by negative thoughts and
emotions that can limit them and hold them back from reaching their full
potential in life.
These things are usually fobbed of with a pill of some sort but proper
exercise can act as a counter balance or ballast and dissipate and soothe
those negative feelings before they can become a problem.
When our body carries out vigorous physical movement it makes us feel
good about ourselves and can help us get back in touch and calm the inner
self. When we work our muscular system with proper exercise natural
chemicals are released that regulate emotions and thoughts and dissipate
stress. Your exercise program oils the wheels that turn in our brains for
everything from the way we think, to what we feel and what we do.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 40
And we get a bonus as when oxygen rich blood is pumped around our body
it benefits every single cell, tissue and organ including the brain. This gives
the software in our brain a boost in power which stimulates energy to the
rest of the body. This is why you feel so good after an exercise session. If
you are tired, fatigued or stressed an exercise session can rejuvenate you in
a very short time.
Exercise is a simple inexpensive gift we all have access to and can give
ourselves. The investment will pay off in multiple ways right throughout
our life.

Chapter Three
Your Brain On Food
We have talked at length about the role of exercise in brain health and now
we are going to cover the role of food.
As a society, we are used to the idea that we feed our bodies, and that our
diet shapes our waistlines. But many of us forget that the same diet also
feeds our brains, and that the food we give our brains shapes our thoughts
and actions.
Every bite of food you eat is a choice that either depletes or nourishes
your brain.
The wrong foods - like sugar and trans fats - can leave you feeling mentally
foggy, anxious, and depressed, while the right foods can help make you
mentally sharp, positive, and productive.
Foods that are rich in essential brain nutrients will protect you against a
variety of mental disorders now and degenerative brain diseases in years
to come.
Day after day, the foods we eat are broken down into nutrients, taken into
the bloodstream and carried up into the brain. Once there, they replenish
depleted storage, activate cellular reactions and become the very fabric of
our brains.
The brain is the hungriest organ in the body, consuming more than 20
percent of your body’s total energy haul. At the same time, our brain cells
are irreplaceable. Unlike the rest of the body, where cells are continuously
replaced, the vast majority of brain cells stay with us for our entire lives –
which means they are in need of extra care and nourishment.

Next-generation medical imaging and genomic sequencing studies have
helped us understand that some foods play a neuro-protective role,
shielding the brain from harm. It’s no surprise that, conversely, other
foods are harmful for the brain, slowing us down and increasing the risk of
cognitive decline.
If we stop and think about it. Our brain is always “on.” It takes care of our
thoughts and movements, our breathing and heartbeat, our senses - it
works hard 24/7, even while we are asleep. This means our brain requires
a constant supply of fuel. That “fuel” comes from the foods we eat, and
what’s in that fuel makes all the difference. Put simply, what you eat directly
affects the structure and function of your brain and, ultimately, your mood.
Like an expensive car, your brain functions best when it gets premium fuel.
Eating high-quality “nutrient-dense” foods that contain lots of vitamins,
minerals, and antioxidants nourish the brain and protect it from oxidative
stress which is the “waste” (free radicals) produced when the body uses
oxygen, which can damage cells.

Today, fortunately, the expanding field of nutritional science is finding
there are many consequences and correlations between what you eat, how
you feel, and how you ultimately behave.
1. Sugary Drinks
Sugary drinks include beverages like soda, sports drinks, energy drinks and
fruit juice not only expands your waistline and boosts your risk of type
2 diabetes and heart disease - it also has a negative effect on your brain
causing brain inflammation and impairing memory and learning.
2. Refined Carbohydrates
Refined carbohydrates include sugars and highly processed grains, such as
white flour as they generally have a high glycemic index (GI). This means
your body digests them quickly, causing a spike in your blood sugar and
insulin levels.
They also have a high glycemic load (GL). The GL refers to how much a food
raises your blood sugar levels, based on the serving size. Foods that are
high-GI and high-GL have been found to impair brain function.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 45
Research has shown that just a single meal with a high glycemic load can
impair memory and intelligence in both children and adults. This effect
on memory may be due to inflammation of the hippocampus which is
now recognized as a risk factor for degenerative diseases of the brain
like dementia.
For example, one study looked at people who consumed more than 58
percent of their daily calories in the form of carbohydrates. The study found
they had almost double the risk of mild mental impairment and dementia.
Studies have found that when people consume higher amounts of trans fats,
they tend to have an increased risk of Alzheimer’s disease and dementia,
poorer memory, lower brain volume and cognitive decline.

4. Highly Processed Foods
Highly processed foods tend to be high in sugar, added fats and salt and
include foods such as chips, sweets, instant noodles, microwave popcorn,
store-bought sauces, ready-made meals, biscuits, crisps, and frozen pizza,
as well as many snacks. Then there are all of the margarines and commercial
cheeses, along with other spreadable or “creamy” products. Ditto for
processed meats such as salami, bologna and frankfurters. The more of
these processed foods you consume on a regular basis, the higher your risk
of cognitive decline and dementia.
These foods are usually high in calories and low in other nutrients. They’re
exactly the kinds of foods that cause weight gain, which can have a negative
effect on your brain health.
One of the ways processed foods may negatively impact the brain is by
reducing the production of a molecule called brain-derived neurotrophic
factor (BDNF) as we have talked about in previous chapters of this
eBook. This molecule is found in various parts of the brain, including the
hippocampus, and it’s important for long-term memory, learning and
the growth of new neurons. Therefore, any reduction can have negative
impacts on these functions.
5. Aspartame
Aspartame is an artificial sweetener used in many sugar-free products.
People often choose to use it when trying to lose weight or avoid sugar
when they have diabetes. It is also found in many commercial products not
specifically targeted at people with diabetes.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 47
Phenylalanine can cross the blood-brain barrier and might disrupt the
production of neurotransmitters. Additionally, aspartame is a chemical
stressor and may increase the brain’s vulnerability to oxidative stress.
Studies have revealed these factors may cause negative effects on learning
and emotions. As well as adding an increased risk of stroke and dementia.
Best to avoid all artificial sweeteners and excess sugar from your diet
altogether.
6. Alcohol
When consumed in moderation, alcohol can be an enjoyable addition to
social situations or a nice meal. However, excessive consumption can
have serious effects on the brain resulting in a reduction in brain volume,
metabolic changes and disruption of neurotransmitters, which are chemicals
the brain uses to communicate.
You would have heard the old wives’ tale that alcohol kills brain cells.
And while that anecdote may seem dramatic, it’s not that much of an
exaggeration. A study published in The British Medical Journal found that
even moderate drinking, which they defined as about 6-9 drinks a week,
can damage the brain, including hippocampal atrophy. This study prompted
recommendations of no more than 14 units, or about 6 drinks, per week to
reduce risk of brain damage.

Chapter Four
News Flash!
Technology Is Ruining Your Brain
and Posture
You may have noticed a friend appearing scatter-brained and stressed out
or you may have even experienced it yourself. In today’s age, it’s common
to dismiss our flustered life (and brain) as normal. But it’s not normal.
While technology use can help promote the development of the left side
of the brain in the form of linear and rational thinking, the right side of the
brain can be severely compromised.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 50
Damage to the right side of the brain is found with digital dementia as
the emotional, perceptive, and resourceful right side of the brain becomes
underdeveloped. This is associated with deficits with short-term memory,
attention span, the ability to concentrate and regulate emotions, insomnia,
and emotional disturbances such as anxiety and depression.
Over time, this posture will cause significant damage to the spine, in what
is otherwise a preventable injury as for every inch the head moves forward
the weight of the head on the spine increase by an additional ten pounds.
Along with back pain and headaches, Tech Neck or Forward Head Posture
causes dysfunction in the brain stem leading to an imbalance in the wiring
circuitry of the brain. Your neck is literally the BRIDGE between your head and
your body. It’s the balance beam from which good healthy posture originates.
The end result of this scenario are symptoms such as insomnia, depression,
anxiety and/or mental sluggishness and finally, permanent cellular death
in your brain.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 52
The term “Digital Dementia” was coined by top German neuroscientist
Manfred Spitzer and used to describe how the overuse of digital technology
is resulting in the breakdown of cognitive abilities in a way that is more
commonly seen in people who have suffered a head injury, psychiatric
illness, or Alzheimer’s.
Think about it... when was the last time you had to memorize a phone
number? While many of us grew up remembering phone numbers and
other important information, most people today don’t need to remember
anything because we have devices that do it for us. And if you can’t recall
a piece of information, instead of spending the extra few minutes to recall
that information organically – by accessing our natural memory and using
our brain – we just go look it up on Google.
The human brain is plastic and adaptable and always changing in response
to the environment. Children’s brains are particularly adaptable in
development, which is now when the brain is most exposed to technology.
Young people are now being born into a world where it is normal to spend
an average of 8 hours each day exposed to digital technology. This exposure
is rewiring their brain’s neural circuitry in a negative way.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 53
We spend our lives with our hands in front of our body (accessing our digital
devices, driving, eating and so on). Therefore, muscles like the pectorals
(chest muscles) can become tight and you can lose important extension in
your mid back and external rotation in your shoulders.
Any muscles that are stretched out for a long period of time can become
weak. We are talking days/ months/ years, here. The stabilizers of your
cervical spine are no different. When your mid back is rounded and stiff,
and your head is jutted forward, the stabilizers that support a healthy head
position become lengthened and weakened over time.
The modern approach to preventing tech neck in the digital age is very
simple. It means building strength. Strength rules, and if you keep your
muscles strong and flexible, they are going be less likely to become short
and cause health issues and pain.
The real cause of neck and lower back pain from phone and computer usage
is weakness in muscle systems. To fix or avoid Tech Neck, you must increase
muscular capacity to hold your head in a healthy position for long periods
of time.
So the solution is really simple to fix Tech Neck. Just strengthen your entire
body and your posture is immediately helped.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 54
Perhaps also consider a digital sabbatical - although it’s not easy or ideal
for most of us who are ‘plugged in’ due to our jobs and the needs of the
modern world, we should, at the very least unplug during the weekend.
Work can - and should - wait. Social media can wait.

Conclusion
No matter your age, protecting your brain health should be a priority so we
can turn the tide on the epidemic of neurodegenerative disease.
And, not surprisingly, physical exercise, is taking center stage. Only proper
exercise is empowered to produce changes that both strengthen and
renew the body and the brain, especially in areas directly associated with
both memory and learning.
In other words, proper exercise is the primary key towards building a brain
that not only resists shrinkage but increases cognitive abilities by promoting
neurogenesis – the brain’s ability to adapt and grow new brain cells.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 56
So, the more you exercise, the more BDNF is produced, resulting in the
production of new brain cells.
The fact that physical exercise and brain health are so closely related is
not new information. This fact has been known by scientists for years and
ongoing research continues to support these findings.
Just as other muscles require stimulation to stay healthy and strong, brain
cells need to be worked to stimulate them to grow and maintain strength
as well. We do that with proper exercise shunting blood, elevating oxygen
levels and growth factors to the brain and boosting the production of
important nerve-protecting compounds; reducing damaging plaques in
the brain and promoting survival and development of neurons – a process
known as neurogenesis or neuroplasticity.
The cumulative effects of this process, over time, slows down and impedes
brain aging.
That means there’s no time like now to get strong and fit. Our everyday
habits, and how we utilize our daily energy output, determines whether
we contribute to our mental and physical health or subtract from it. So,
ultimately, for the most part, the healthy longevity of our mental state/
brains, just like our bodies, is resting in our hands.
Lucky for us, improving and sharpening our cognitive abilities and
strengthening our memories (like strengthening our bodies) is as close as
our neighborhood gym or challenging, workout routine.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 57
What works wonders for the body will work wonders for the brain because
they operate as one unit, not in isolation! What we do with our body does
and will impact our mental faculties now and in the future.
So, if a healthy, fit and active, energy driven body is not enough to motivate
you to proper exercise, then possibly enjoying strong cognitive skills and a
healthy memory will!
Optimizing health and longevity, for both the body and brain is about eating
the right foods and avoiding the wrong ones. It’s about keeping your body
moving and avoiding the unenviable fate of the couch potato.
Yes, you can go it alone and try to figure out by yourself the best way to
immunize your brain against the ravages of age. But you’ll save yourself
years of time and effort when you adopt the shortcuts afforded by a carefully
thought out brain health blueprint. One that has been crafted to provide
you with the maximum brain-protecting benefits for the least amount of
mental and physical investment.
How To Build A Better Brain And Slow Cognitive Decline Carolyn Hansen© 58
But its work that is well worth the investment considering the alternative,
which is a world of slow cognitive decline marked by lost memories and
growing mental confusion from which there is no way back once you come
under its influence.
So, if taking steps to ensure brain health resilience in the years ahead sounds
like something you’d like to know more about, please come check out my
program. I have much more to teach you.
To your health…always!
