There are all these cases today of sizable percentages of the population being pre-dispositioned to do things that currently make no sense. ADHD is one. Is ADHD a defect? Or an adaptive response that is no longer needed? Or just a different kind of personality maturation pattern? Perhaps heavy alcohol inebriation was needed when you worked 35 years barely staying alive, then died of measels. Perhaps it's part of intelligence -- some addiction researchers are now saying that addicts are actually "over-learning" the stimulus-response associated with drinking. Like I said, beats me. But it is fascinating -- even more so if there is 10% of the population who are adults and presumably mostly feel they have no problem while the rest of us think they do. Obesity is developing along similar lines -- except the 10 percent are going to end up being the folks who aren't fat! Personal anecdotes are great, and I congratulate anybody on overcoming something that they've identified as a problem. But when we're talking 10 percent of the population? There's something else at work here; something that has developed over eons across populations worldwide. Fascinating stuff.
