You can extend the warranty of your frame - muscles, bones and joints - and live longer and look better. It's tough to get spare parts.

I was listening to what my knee said. I knew what exercises to do, what I could tolerate and when to regress.

It may actually interfere with normal muscle functioning. That data hasn't been real strong, but there is some suggestion there may be a little negative to wearing a brace as well.

I would say a brace should be a secondary consideration,

Your body is more vulnerable as you age. So things you did before, you might not be able to withstand now.
