Keep active--do the 30 minute cardio walk, work your way up with dumbbells till you get a routine with at least 15 pounders, do some stretching exercises.
I moved down from 12 ga. to 20 gauge. It's no big deal because 20 ga. has plenty of stopping power.
When joint pain is bad I try not to go out in public alone because I know the crooks smell weakness. When I feel good I make up for it.
Yes I can't run or kick like I used to, so more caution is in order. Go armed as much as you can, even if it's only a walking stick.
