Instead of seeking that "evidence," consider this: is the average geek not supposed to be smarter than the average person? (Is this generality more acceptable because it's flattering? For that matter, is there any evidence of this, either? But for now, let's assume it's true.)

So on that assumption, which we grant temporarily, why then should we not expect these smarter people to make smarter lifestyle choices? Should we not expect geeks, in other words, to do better, not just the same as?

Or at the very least, to be armed with the correct information so that, when the time comes to make those choices, he at least recognizes when he is choosing poorly? Of course the real question is: how do we get people (smart people included) to choose wisely? This is the sixty-four thousand dollar questions.
