Johnny Knoxville has 20 doctors' phone numbers in his mobile phone.

The 42-year-old daredevil - who performs several dangerous stunts on each episode of reality series 'Jackass' - has suffered many injuries throughout his career, but insists he doesn't ''give a s**t'' about getting hurt because he is so used to it.

He said: ''I've got 20 doctors' numbers in my phone! Recently, I fractured my elbow and right now I have a torn shoulder.

''My left side's my impact side so it's all f***ed. And my back's blown out but I don't know what else to do besides move forward. It's what I do and a big part of it, so I don't really think about it.

''And I have asthma! But I don't give a s**t - I'm fine with it.''

The stuntman doesn't worry about getting hit after provoking someone during one of his pranks, and is far more concerned about fans suing him if they punch him and hurt themselves.

He added to Nuts magazine: ''I don't give a s**t about being punched, but I don't want someone to hit me wrong and then their knuckle hurts, so they sue us.

''In America there are lots of lawsuit, so when I'm trying to get someone angry I'll bring 'em back down. Then I'll get 'em angry again, and bring 'em down.''
