I do Bowls, Golf, Taichi, Yoga intermittently as well as basic calisthenics at home (although I do some of the more strenuous ones now as well on top of these). My philosophy with sports and exercise is that one can only do Football, Rugby, Tennis for so long before it's physically impossible to do, but with the so called 'old' sports well, if you KNOW these are the end point, if you KNOW this is where you will end up being the only thing you can do, then I figure, why not get a 30 - 40 year head start? Then when my old school/work compatriots are just getting into it, I've got 30 - 40 years of experience and practice on them. At that point they can suck my wrinkly balls after their defeat as I jump on my mobility scooter, subwoofer on the back and two of the nurses from the home to give me a sponge bath when I get back.
