Science has officially proven that Ozzy Osbourne is a mutant. The 66-year-old rocker has claimed to do every drug in the books, but despite his hard lifestyle, Ozzy Osbourne is still as healthy as ever. According to genome experts, Osborne might have his mutant genes to thank for it, reports the Spreadit.

Last July, scientists sequenced Ozzy’s genes, now referred to as the “Full Osbourne Genome,” because, as head scientist Nathaniel Peason put it, “Why not Ozzy?,” reports WAAF. Peason, who sequenced the rocker’s genome, discovered that the “Full Osbourne Genome” contains several variants that “we’ve never seen before.” These mutant variants could impact how Ozzy absorbs recreational drugs.

Ultimately, sequencing Ozzy Osbourne’s genome might prove to be medically valuable, and his mutant genetic code “could mean potential breakthroughs in the world of medicine,” according to WAAF. Although initially hesitant to allow scientists to track his genome, Ozzy Osbourne was persuaded that it might further science, and started to favor “the idea of offering the mysteries of his DNA to science.”

Scientists discovered that the Osbourne genome mutated to better handle his drug abuse. Experts from Cambridge, Massachusetts, explained, according to WAAF:

“He had a change on the regulatory region of the ADH4 gene, a gene associated with alcoholism, that we’ve never seen before. He has an increased predisposition for alcohol dependence of something like six times higher. He also had a slight increased risk for cocaine addiction, but he dismissed that. He said that if anyone has done as much cocaine he had, they would have been hooked.”

Sharon Osbourne, who is married to Ozzy, isn’t surprised to find out her husband is a mutant. Osbourne reportedly said of her mutant husband, “I’ve always said that at the end of the world there will be roaches, Ozzy and Keith Richards. [Ozzy will] outlive us all. That fascinated me – how his body can endure so much.”

Ozzy himself was curious to know how he could put his body through so much, yet still be alive. “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.” Turns out, he’s just a mutant.

In his autobiography, the mutant Ozzy Osbourne detailed his drug use, and his shock that he’s still on Earth. “Every day of my life has been an event. I took lethal combinations of booze and drugs for thirty f**king years. I survived a direct hit by a plane, suicidal overdoses, STDs. I’ve been accused of attempted murder. Then I almost died while riding over a bump on a quad bike at f**king two miles per hour.”
