When Puberty Ends

I heard a 23-year-old woman complain: “I must be getting old when 11:00 at night is late.” It got me thinking.

It turns out that the explanation for why teens are natural night owls has recently been elucidated. They can’t help it — they just don’t get tired until way later in the evening. Then, of course, their bodies want to stay asleep well into the next morning in order to feel sufficiently rested. Since most of them are stuck with the artificial structure of school hours, they’re screwed — and condemned to suffer constant fatigue from cumulative sleep deprivation. Old news.

Then I started wondering about the back end of this phenomenon. Even though our American “youth culture” attributes great coolness to late-night happenings, since this pubertal sleep shift is biological, there must come a point at which their pineal glands go back to releasing melatonin at a more reasonable hour. Does 10 years sound about right? I remember not being nearly as enamored of the “all-nighter” by the time medical school rolled around, as opposed to college, where staying up all night was a regular occurrence. Certainly by residency (ages 26 to 30), it was a killer. Read more »

A Secret “Sign Of Aging”: International Disease Mongering

Just five days ago we wrote about an American journalist’s observations of medicalization of one problem sometimes observed after menopause: Vaginal atrophy.

Today we see that this disease-mongering trend has popped up in Australia as well. This should be no surprise. Such campaigns are usually led by multinational pharmaceutical companies and their advertising and public relations agencies.

What caught our eye was an article on a women’s health foundation website — a foundation that posts a pretty thin excuse for why it won’t tell you its source of funding. Its article on vaginal atrophy uses classic disease-mongering language:

Ask a woman over the age of 50 about the ‘signs of ag[e]ing’ and she’ll most likely lament about grey hairs, wrinkles and certain body parts having lost their youthful perkiness. What she probably won’t mention is that is that things are ageing “downstairs” too; up to 40% of postmenopausal women show signs of vaginal atrophy.”

The silent epidemic that no one talks about. The huge prevalence estimate — where does that 40 percent figure come from? Read more »

The Spirit Of The Place: Samuel Shem’s New Book May Depress You

When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
