Actually it's not even the herd-thinning aspect that's most interesting, it's the notion that 82 deaths over the course of thirteen years is somehow statistically significant enough for the CDC to be spending time and effort looking into it. Hundreds of times as many teenagers have died in the same time period from car accidents, gun accidents, off-road vehicle accidents, suicide. And according to Google News, right now there are 319 news articles on this "story" -- nearly four times the number of actual deaths over the past decade-plus. I suppose a sense of proportion is, as always, too much to ask for.
