I keep making these "To Do" lists but nothing gets crossed out

I've been too swamped to comment on any of the following articles, all very interesting:

Shy on Drugs

It may seem baffling, even bizarre, that ordinary shyness could assume the dimension of a mental disease. But if a youngster is reserved, the odds are high that a psychiatrist will diagnose social anxiety disorder and recommend treatment.

Do We Really Know What Makes Us Healthy?

Many explanations have been offered to make sense of the here-today-gone-tomorrow nature of medical wisdom — what we are advised with confidence one year is reversed the next — but the simplest one is that it is the natural rhythm of science. An observation leads to a hypothesis. The hypothesis (last year’s advice) is tested, and it fails this year’s test, which is always the most likely outcome in any scientific endeavor. There are, after all, an infinite number of wrong hypotheses for every right one, and so the odds are always against any particular hypothesis being true, no matter how obvious or vitally important it might seem.

This Is Your (Father’s) Brain on Drugs

A SPATE of news reports have breathlessly announced that science can explain why adults have such trouble dealing with teenagers: adolescents possess “immature,” “undeveloped” brains that drive them to risky, obnoxious, parent-vexing behaviors...We know the rest of the script: Commentators brand teenagers as stupid, crazy, reckless, immature, irrational and even alien, then advocate tough curbs on youthful freedoms...More responsible brain researchers...caution that scientists are just beginning to identify how systems in the brain work...Why, then, do many pundits and policy makers rush to denigrate adolescents as brainless? One troubling possibility: youths are being maligned to draw attention from the reality that it’s actually middle-aged adults — the parents — whose behavior has worsened...What experts label “adolescent risk taking” is really baby boomer risk taking. It’s true that 30 years ago, the riskiest age group for violent death was 15 to 24. But those same boomers continue to suffer high rates of addiction and other ills throughout middle age, while later generations of teenagers are better behaved. Today, the age group most at risk for violent death is 40 to 49, including illegal-drug death rates five times higher than for teenagers.
