 70% was as good as it would get. So because I'm down to a millimeter of joint space in my knee and it's degenerative. That's still significant. Oh, so much better because I can do so many activities that I couldn't before. And this is now, we're approaching a decade since I started doing that. I thought I was going to have to have a knee replacement a long time ago, but still keep on going. And they say that really is painful. So what other conditions can it help?
