Clint Eastwood says growing old is a fun process at times.

"Am I aging? The pros and the cons? Well, you know a lot more, at least until the time you start forgetting it all," he said in an interview with Collider.

"Actually, aging can be a fun process, to some degree. But, ask me a year or so from now, and I'll try to give you the same answer."

Eastwood, who turned 82 in May, is committed to staying in shape.

"I exercise a lot. I play golf with (Trouble with the Curve co-star) Mr (Justin) Timberlake," he said.
