There can only be one way to explain why the 60-something-year-old Black Sabbath rocker is still alive. He's not human.

According to ABC news, he's a genetic mutant. Ozzy's lived an incredible life and done an incredible amount of drug and alcohol-related damage to himself. It's a wonder he's still alive. Even Ozzy Osbourne wondered why he's still rockin'.

"I was curious ... given the swimming pools of booze I've guzzled over the years -- not to mention all of the cocaine, morphine, sleeping pills, cough syrup, LSD, Rohypnol ... you name it -- there's really no plausible medical reason why I should still be alive. Maybe my DNA could say why.

What doctors found was pretty amazing. Geneticist Nathaniel Pearson found that Ozzy has a bunch of gene variants that "we've never seen before." The article also said that:

Not surprisingly, the most notable differences in Osbourne's genes had to do with how he processes drugs and alcohol. Genes connected to addiction, alcoholism and the absorption of marijuana, opiates and methamphetamines all had unique variations in Osbourne, a few of which Knome geneticists had never seen before.

There you go, Ozzy really is Iron Man!
