Rocker Ozzy Osbourne has agreed to allow scientists to test his genetic code so they can determine how he has survived years of hard partying.
The 61-year-old Black Sabbath star struggled with an addiction to alcohol and prescription drugs over the years, and has admitted drinking "four bottles of cognac a day" at the height of his heavy boozing.
Osbourne has called his survival into his 60s a "medical miracle" and admitted earlier this month (Jun10) that he'd like to donate his body to doctors and scientists after he dies so they can find out how he managed to stay healthy.
And now the Paranoid hitmaker has taken the first step towards getting answers - he's signed up to become one of the first humans to participate in a $40,500 (£27,000) test which will map his genetic code using a blood sample.
Nathan Pearson, of the U.S. company behind the test, Knome, says, "Analysing individuals with extreme medical histories has great potential scientific value."
