...Mind, it does seem to be a case of both a small sample biasing the data, and having enough people clumped at the very young end to seriously depress the average age. Granted, 10 percent of a sample is a notably higher mortality rate than the general population in a given age group. And I think the accident issue may confuse things a bit; how many of the accidents are directly attributable to the rock-n-rollness of it all?
(Though, looking at it, what I wonder is how many of the rock'n'rollers wind up taking other people with them. Does associating with these musicians shorten the lives of hangers-on and other people?
And, given that the mortality rate of younger popsters is dropping, apparently the whole Just Say No thing is sorta kinda taking hold -- Lindsay Lohan aside. Apparently, younger popsters are indulging at ever lower rates.
And for those who don't say no, there's always Celebrity Rehab!...
