Knee replacement is serious stuff. And it actually could have made me worse

And about in the late '80s, I got kind of burned out a little bit.

I got kind of burned out, so I moved to Florida. I was down there for 10 or 12 years, raising children.

I have done a series in the '60s, '70s and '80s.

I figured my body always would be able to repair itself. I think all of us believe that - until you begin to age and get hit with deteriorating joints.

I just turned 66, and I'm starting to work again.

I have twin boys, 12, and a daughter, 17.
