Thanks for the advise on diving. I definitely plan on checking it out - my brother would be pleasantly surprised. I am in pretty good shape and have great lung capacity. Always been a success in athletics and sports. Dancing is also good for endurance and I do a lot of it.
Dancing is also very social and Samantha, Divemaster, if you take it up you are bound to make new friends. Where I take lessons, 70% are singles and most are professionals (yes, and attractive). Cheers .....Jim.
