Hi @thudson1965, I think I'm one of those members who have talked about walking. I do it daily if possible. And if it isn't as possible on a day I try to get at least some walking in.
It's a low-impact aerobic and it's a relatively easy way to keep fit without feeling you have to pump iron for 50 hours a week. For those recovering from surgery, prostate or any other kind of surgery or from an illness, always talk to your doctor first and see if walking as an exercise can even be recommended in your case. Then start out slowly. Maybe a half mile the first few times and gradually you'll be able to do more distance and build up your stamina. Before you seriously get into this, get in your car and drive a course that you think you might like to walk. That's just to find out how many miles it is and you will have a better idea of what will work.
But the best thing is you get ou9t and get fresh air and that in itself makes you feel good. And you see, hear, and smell so much more than you would by driving somewhere.
As for the incontinence aspect, best thing to do is to figure out the level of protection you would need. Since most of us are coming into colder weather (we even have some of that in Florida!) it may be good to wear more than what you think you might need. And go by the philosophy that it's better to have it and not need it than to need it and not have it!
