I would suggest you start with the idea that staying 'injury free'...is almost impossible.

Even small injuries, seem to affect activities in one way or another...and can be a bummer.

As mentioned above, the best way to minimize the chances of a severe injury is to stretch, warmup and limit total time spent on the sports that have the most impact on joints...which is our weak points as we get older.

As they say..."getting old isn't for wussies."
