Ozzy's genes examined

ST. LOUIS: Alcohol and drug abuse has killed too many rock stars to mention, but at 61, Ozzy Osbourne is going strong.

Now DNA researchers in St Louis say they're trying to discover why decades of substance abuse didn't take down the Prince of Darkness.

Jon Armstrong, chief marketing officer for St Louis-based Cofactor Genomics, said Osbourne has asked a human genomics company to map his DNA, with Cofactor's help.
