Ozzy Osbourne refuses to live in a vegetative state and told his wife, Sharon Osbourne, to "pull the plug" if he ever falls into a state of coma. The former Black Sabbath frontman has called his survival into his 60s a "medical miracle" after years of hard partying and a grim quad bike accident in 2003.

Osbourne admits that he would prefer his wife to turn off his life support system should he acquire an extreme brain damage and could no longer look after himself.

"I've always told Sharon, 'If I become one of my vegetables (sic), you have my permission to pull the plug.' People say that's going against God, but being a doctor is going against God, isn't it? If you've got a headache, it ain't God who reaches down and gives you the aspirin," he wrote in his health column for Britain's Sunday Times magazine.

The rock icon said that he supports the controversial practices of Dr. Jack Kevorkian, a known euthanasia activist, but believes that strict regulations should be established before doctors can practice 'mercy killings'.

"To a certain degree, I can understand Kevorkian when he says doctors should be able to help their patients top themselves," he said.

"But knowing America the way I do, if it became legal, someone would end up doing a deal: y'know, 'If you pop my nan, I'll give you 25 per cent of the inheritance' kind of thing. There are certain doctors over here - anywhere, probably - who'd kill you for 10 grand. Then you'd have aged relatives who'd feel pressured into taking the death juice 'cause they wouldn't want to be a burden. So I'd want there to be some kind of process, not just squeeze-this-trigger-and-you're-gone, see ya."
