Paris Fashion Week Womenswear Fall/Winter 2015/2016 - Stella McCartney Show

Sir Paul McCartney is passing on grass these days.

The Beatles member – who has four grown children and 11-year-old daughter Beatrice – says he no longer smokes marijuana.

“I don’t do it anymore,” the legendary musician, 72, told the Daily Mirror. “Why? The truth is I don’t really want to set an example to my kids and grandkids. It’s now a parent thing.”

“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,” he added. “Instead of smoking a spliff I’ll now have a glass of red wine or a nice margarita. The last time I smoked was a long time ago.”

With five children and eight grandchildren, McCartney keeps fit and healthy for his family.

“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,” he shared. “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. And then standing on my head.”

And he is loving his regular exercise routine.

“What’s cool about it is that I’ll be in the gym with all these guys doing really big weights, while I’m there doing not big weights,” he explained. “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!’”
