Andy,
Just make sure you consult your doctor prior to vigorous excercise. Most of these clubs we lurk around don't have defibulators on site. And pop a few Boneva's once in a while so we don't break our hips and we can extend our adolescence a few more decades hopefully. Yea, I understand the position you are in. Sometimes when talking to coworkers I realise how out of wack I am with popular culture. It's empowering and concerning at the same time. But then I have some friends who are stuck in time and actually very close minded to anything outside the realm of what they have been listening to for a zillion years now. Even though they are far from mainstream they are still trapped in a rigid uniform/lifestyle if you will. So I think the answer to your question is the cut off age is when you are doing it because it is what you have always done vs. what you are still feeling. Which for most of us here may mean never.
