I've a friend in England who's a GP and he smokes cigars.. His philosophy is why live healthily with the goal of adding 5 years onto your life. He says these 5 extra years come in at the end where you don't want them rather than in the middle - where you do. I find that a compelling argument!
Me? I row 3 times a week - I average ~40km/week. A sport you can do sitting down. Highly recommended. I once read that it's second only to swimming for its health benefits. For sheer enjoyment, I'd rate it #1. It enables me to enjoy life as I want - wine every day and yes, the occasional cigar.
