Ozzy Osboune is the Toxic Avenger

The legendary 61-year-old singer of Black Sabbath has allowed his DNA to be sequenced. As it turns out, there's a reason he's not dead yet. According to an article in the Sunday Times, he has gene varients that researchers have never seen before- some that enable him to do toxic amounts of drugs. The particular genes identified are associated with an increased tolerance and risk for alcoholism and methamphetamine addiction. The genes actually influence how Ozzy's body absorbs the drugs. He was six times more likely to be an alcoholic. He is also more likely to have hallucinations from smoking pot. The funny thing is that while he can consume copious amounts of illicit drugs, his body can't metabolize caffeine correctly. The researcher states that Ozzy's ADH4 gene "had a change on the regulatory region". It does not explain if this was inherited or some kind of epigenetic change as a result of all the drugs and booze he did. It's a question of which came first. Did Ozzy toxically poison himself producing a genetic mutant or did his parents pass on that gene?
