Yes swimming is the best if you can find a place to do it. I used to swim in the ocean a couple time a week, I think the salt water also has a healing effect on your body. I can't anymore except in summer when it flattens out as I can't handle getting in and out when it's rough. If it knocks me down, I'm screwed! I used to be a member of the local YMCA here but I let it laps as I just didn't use it enough. I just work to much and get too tired, drive right past the Y to get home for a nap! I wish I still had the energy, I'd join again. I also have a couple outdoor pools around here that I can use but they are not heated and my old broken body just can't handle that cold water anymore so I'll b waiting for summer to get back in the swim! Goo dluck!
