Rolling Stone guitarist Keith Richards has claimed he is perfect health after undergoing brain surgery and added that he wants to live to 150.

The rock and roll legend underwent brain surgery following an accident when he fell out of a tree last year.

Talking about his operation, he told Mojo magazine: "The doctors came back with this sort of amazed look on their faces, like heart, liver, kidneys, all perfect."

Richards, who has outlived both his parents, added: "Mind you, I'm looking to be a good 150 before I think about croaking."

Discussing the side-effects of the brain op, the rocker commented: "The drug I'm on now because of the brain job, Dilantin, means you can't take cocaine any more, which is fine for me. I mean, I haven't seen coke for, like, a year and a half.

"I still smoke like a f***ing chimney. Get me some good weed."
