OK I do like golf, but dont play it enough to count. But it is a good exercise.
Recently my wife and I have gone back to swimming. We havent done this for a long time, once we were very good swimmers. But for our age, early sixties, its an exercise we can easily cope with.
We do walk our dogs, or at least the dogs walk us!
As one gets older I beleive exercise is still important, but has to fit our ages.
For us, errrrr, more mature people, what exercise do you recomend? participate in yourself?
