The medical history or (medical) case history (also called anamnesis, especially historically) (often abbreviated hx or Hx) of a patient is information gained by a physician by asking specific questions, either of the patient or of other people who know the person and can give suitable information (in this case, it is sometimes called heteroanamnesis), with the aim of obtaining information useful in formulating a diagnosis and providing medical care to the patient. The medically relevant complaints reported by the patient or others familiar with the patient are referred to as symptoms, in contrast with clinical signs, which are ascertained by direct examination on the part of medical personnel. Most health encounters will result in some form of history being taken. Medical histories vary in their depth and focus. For example, an ambulance paramedic would typically limit their history to important details, such as name, history of presenting complaint, allergies, etc. In contrast, a psychiatric history is frequently lengthy and in depth, as many details about the patient's life are relevant to formulating a management plan for a psychiatric illness.

Oxybenzone or benzophenone-3 (trade names Milestab 9, Eusolex 4360, Escalol 567, KAHSCREEN BZ-3) is an organic compound. It is a white solid that is readily soluble in most organic solvents. Oxybenzone belongs to the class of aromatic ketones known as benzophenones. It is a component of many sunscreen lotions.

Structure and electronic structure

Being a conjugated molecule, oxybenzone absorbs at lower energies than many aromatic molecules. As in related compounds, the hydroxyl group is hydrogen bonded to the ketone. This interaction contributes to oxybenzone's light-absorption properties. At low temperatures, however, it is possible to observe both the phosphorescence and the triplet-triplet absorption spectrum. At 175 K the triplet lifetime is 24 ns. The short lifetime has been attributed to a fast intramolecular hydrogen transfer between the oxygen of the C=O and the OH.

Production

Oxybenzone is produced by Friedel-Crafts reaction of benzoyl chloride with 3-methoxyphenol(3-hydroxyanisole).

Jude Cole and Scott Hendricks produced the album, with additional production from Chris Farren on "What Was I Thinking Of".

Critical reception

William Ruhlmann of Allmusic rated the album three stars, comparing its sound to southern rock on some tracks but saying "there's nothing here that's particularly striking from a creative standpoint."Entertainment Weekly critic Alanna Nash rated it B+, comparing Davidson's vocals to Delbert McClinton and calling the album "a tender-tough charmer."

Content

The song begins with a young man coming home from a bar with "liquor on [his] breath". After an argument with his father about how he must abide by his rules, he leaves saying "I hate you." His father then explains: "You can't stop my love for you / It will be here, that's a given / As long as I am living on this Earth / One thing is true / You can turn away, forget me / Curse my name, but love won't let me let you go / Son, always know / My love is unconditional."

In the second verse, the young man is reflecting on his wife leaving him saying "I hate you" a year later and realizes what his father meant in the first verse. The husband explains the same thing that his father had explained to him — that his love for her is unconditional.
