The Hollywood star Michael Douglas spoke out this week to reflect on the longevity of his career in Hollywood, and to admit that he “used to blame” memory problems on smoking marijuana.

Douglas, 76, confessed that during the COVID-19 pandemic, he’s been doing “much more couch potato–ing” and is “shocked by the reduction of my stamina.”

“My long-term memory is fine, but my short-term memory is not. I used to blame it on pot,” Douglas told told AARP Magazine. “But I’ve got some friends who’ve been smoking as long as I have and have fabulous memories, so I don’t think that’s the issue.”

Douglas is looking forward to getting back to work on “The Kominsky Method” to sharpen those skills once again.

“Work keeps you going, keeps you sharp,” he explained. “Of course, these days I’m looking around the set, like, I’m the oldest person here, man. Where did the time go? But I love the whole process. We’re not doing brain surgery; we’re showbiz. A boundary I do set is “No a–holes.” I don’t work with a–holes. I’ve got no time for that.”

Douglas is hoping that his family, friends, and coworkers will look back and remember him as someone who was both courteous and kind.

“Which are traits you have to work at and rehearse,” he said. “Particularly compassion — I feel a certain responsibility to conduct myself as somebody who has been blessed and fortunate simply because I was born a white male. And also to teach them to be good citizens of the planet. I’m conscious of us all being in this together.”

Last month, we reported that Douglas was loving life as a grandfather.

“Becoming a grandfather has made Michael a ‘warmer’ man,” a source told Closer Weekly, adding that the star’s 3-year-old granddaughter, Lua, and his 2-month-old grandson, Ryder, have “had a positive effect” on the 76 year-old actor.

“Michael is obsessed with Lua and tries to see her whenever he can,” the insider added. “He’s certainly an entertaining grandfather and takes such pleasure from making her laugh by pulling a silly face, playing the tickle spot and chase. He turns into a big kid himself and feels young again.”

“Michael couldn’t wait to meet his new grandson, Ryder,” the source continued. “His heart melted when he first set eyes on him. Ryder is definitely a ‘Douglas’ – you can already see similarities between him and Michael.”
