rocker ozzie osborne has survived massive amounts of drugs and alcohol and is still surprisingly healthy. in fact, it's so surprising that some geneticists asked him to submit a dna sample. at first, he thought they were joking, but eventually he did. this is what they found:

mutations that they'd never seen before, including a genetic predisposition for alcohol dependence 6 times higher than the average, an odd hearing gene variation, a gene for parkinson's, and one that means inefficient processing of caffeine... plus some variants likely linked to a neanderthal or two in his family's genetic history.
