Sixty-four-year-old Rolling Stones front man Mick Jagger says performing is as addictive as sex—which must be why he's been doing it so long. 

"Performing is like sex - it's an addiction. It is why we are out there doing it. But you do have to be careful. To do it well, you can't do it all the time. It has to be the right time.

"It's like when you are young you think you should be having sex all the time. If you are reading a book all you are thinking is, 'Why am I reading a book - why aren't I having sex? I'm wasting my time if I'm not having sex.'"

Hm. We've never thought, that, actually. Maybe we should be reading less? Even though we feel like we should be reading more. But not everyone can be a sexual machine like Mick Jagger.

Oh, and have you ever wondered why Mick is so skinny? In addition to burning all those calories performing in bed and on stage, Mick says he owes it to his diet as a "war child."

"I do some preparation a few months before we go on tour, but nothing special. I think my fitness levels are down to being a war child. That diet was meant to be the best - hardly any fat or sweets."
