All that only to lay the foundation to say: Live. Take care of the biggies like smoking and exercise. Although for me it is impossible, do a person's best not to worry about the rest. Be smart and careful. But you should do that at any age.
IMO- I believe it is a matter of "use it or loose it". I think this is really applicable where balance is concerned. If balance is not maintained by exercise or practice it tends to deteriorate at almost any age.
I really think what we loose as we age is our confidence. If we think we can not do something we can't.
While not at the same level I did when I was younger; I still ski, climb, and try to master wheelies and track stands on my bikes. However, I usually quit trying to keep up with my wife on downhills when we get much above 40mph
