I think swimming would be tough because he has horrible shoulders from too many years sitting at a desk. I guess he could do the breaststroke but I can't imagine him doing a front or back crawl. Both of his sisters already spend the Winter in Florida (one lives there full-time, the other goes down for 4-5 months) so I think he's considering going down for a few months in the Winter. It would be good because then he can walk in the nice weather. Right now it's hard for him to get out because the area they live in doesn't have sidewalks and he can't walk on the beach. Plus my parents are old and complain about the cold all the time which isn't helped by living on beach-front property (the wind off the bay is brutal in the Winter).
