 I'm 57. Ten years from now when I'm 67, I don't want to have less cartilage. I want the same amount. Hey, I'd like a little more, please. That's what makes your knees feel comfortable. I'm taking this joint, Jill, every day. I have no intention of stopping because I like to play my golf. I like my tennis. I like hitting the gym. I like to run around and play with my kids and exercise.
