Swimming and walking

I have to say I love swimming, I'm not sure I have a particularly good style but it gets me from one end of the pool to the other! I can recommend it as an exercise regime and I'm not particularly sporty! I regularly swim 1800m which is just over a mile and I try to do this twice a week if I can. It's a low impact exercise and doesn't make all my joints complain. Years of digging on archaeological excavations can make the joints - particularly the knees I have found - ready to complain about ill-treatment. Also I'm really not built to be a jogger...I'd soon have a pair of black eyes if you catch my drift. I don't look or feel good jogging. So when I'm not swimming I walk. This works, it clears the head when I've been hunched over a computer, it opens up the airways and there are often people to chat to en route. Try it out. It might surprise you!
