I did DM at 53. Timmed swims were tough. My class consisted of 20 and 30 somethings. I had no problem keeping up with them. As Walter said age has nothing to do with it, it's your overall health and fitness. Oh, an by the way, I have a lot of people take me seriously although I have to admit dementia set in about 30 years ago.
Well, I was just speaking from my experiances.
