Ozzy Osbourne plans to donate his body to a museum when he dies.

The Black Sabbath rocker - who has battled problems with drink and drugs over the years - believes he's a "medical miracle" for surviving all the substances he has put into his body and believes his corpse should be shown off at London's Natural History Museum.

He said: "By all accounts I'm a medical miracle. When I die, I should donate my body to the Natural History Museum. It's all very well going on a bender for a couple of days - but mine went on for 40 years. At one point I was knocking back 4 bottles of cognac a day, blacking out, coming to again, and carrying on. While filming TV show 'The Osbournes' I was also shoving 42 types of prescription medication down my neck, morning, noon and night - and that was before all the dope I was smoking in my 'safe' room, away from the cameras. Meanwhile, I used to get through cigars like they were cigarettes. I'd even smoke them in bed."

The 61-year-old star admits his stash of prescription pills and painkillers was so great, friends of his nicknamed him "Dr. Ozzy" and would often pop by for a cure for their ailments.

He explained to the Sunday Times magazine: "Funny thing is, to my friends I've been Dr. Ozzy for years - mainly because I used to be like a walking pharmacy. I remember back in the 80s, when a friend came to me with a leg ache.

"I went to get my 'special' suitcase, pulled out a pill the size of a golf ball and said, 'Here, take this.' It was ibuprofen, before you could buy it over the counter in the UK. He came back a few hours later and said, 'Dr Ozzy, you cured me!'

"The only problem was, I gave him enough to cure an obese elephant. It knocked the bloke out for a month. That was in the old days, of course, before lawsuits were invented. I'd never do that now. Honest to God."
