At 72 years young former Beatle Paul McCartney has put his wild days behind him, admitting that the last time he smoked cannabis was ‘a long time ago.’ Speaking to The Mirror newspaper, Sir Paul revealed that these days he’s now more likely to be caught having ‘a glass of wine or a nice margarita’, rather than smoking a spliff.

"I don't do that any more. Why? The truth is I don't really want to set an example to my kids and grandkids. It's now a parent thing," he told the Mirror. "Back then I was just some guy around London having a ball, and the kids were little so I'd just try and keep it out of their faces."

"Instead of smoking a spliff I'll now have a glass of wine or a nice margarita. The last time I smoked was a long time ago.” During the interview the 72 year old also show off his impressive flexibility, thanks to yoga, even managing to do a headstand!

“That’s my big claim to fame! I ­actually learned it in the 60s, it was a yoga thing, and my argument is I need flexibility not strength,” McCartney said.

“But what’s cool about it is that I’ll be in the gym with all these guys doing really big weights, whilst I’m there doing not big weights, and afterwards, when I’ve done my headstand for about five minutes, these big guys will come up to me and say, ‘That was pretty impressive, man!”

Speaking about his fitness routine Macca said, “I feel pretty fit. I’m not the sort of person who particularly needs a trainer. I’ll just watch what the trainers do and then copy them.”

“I do a bit of the cross-trainer, a bit of running, a bit of cardio and then I do some weights, some abs on the Swiss ball, before ending up on the mat doing a few stretches,” the singer added. “And then standing on my head.”
