According to this blog article, apparently referencing a New York Post article, Iggy Pop, age 61, does Tai Chi to keep himself fit. Some hilarious soundbite-type quotes:

“I saw footage of Chinese people doing that slow motion stuff in the park and I thought, that looks like a nice maturity direction for me,” he told the New York Post.

“To feel good when I was 21, all I had to do was to smoke a joint,” he once observed. “Now I have to turn off my phones and do tai chi for an hour.”

He says: “I do everything my mom used to tell me to do; I’m just 50 years too late.”
