I have been athletic my whole life. I grew up playing the usual sports, but basketball was where i put most of my time. Throughout college i played intramural sports for my fraternity. I was a gym rat and worked in a gym for 4 years while in college as well as being a personal trainer for over a year. I've always been into fitness, health and wellness, but have also always lived by the word "moderation". I don't think twice about smoking a pipe (2 to 3 bowls a day, sometimes less) or drinking on the weekends (even the occasional weekday wine or beer/whiskey) or having the occasional unhealthy fast food meal. I also grew up and have always lived near the ocean. I bodyboarded when i was young and then made the transition to surfing around 14 or 15 and have been doing that for 15+ years now. I also wakeboard and skateboard(longboard).
I currently and for the past 5 or so years train martial arts, specifically Brazilian Jiu Jitsu, Muay Thai, and some MMA to help the guys on our fight team prepare for an upcoming event. I also teach both BJJ and Muay Thai as well and the martial arts take up a large portion of my life outside of work. I like it that way and wouldn't trade any of my training for the world. My pipe smoking doesn't really affect anything and doesn't hinder me in my performance of said martial arts. I have competed in both BJJ and Muay Thai as well and continued with my normal moderate pipe smoking and drinking routine.
Like many have said before, while not good for you, pipe smoking is sure a hell of a lot better than cigs. But shit, even those are a crap shoot. Everyone knows or knows of someone who has smoked cigs their whole life and dies of natural causes at a ripe old age, as well as the guy who never touched a tobacco product or alcohol and dies of cancer wayyyy too young. I don't live my life thinking about dying and listening to the media's propaganda-riddled bullshit regarding smoking.
Tobacco is a big business...The American Cancer Society/Healthcare Industry as a whole is a MUCH bigger business. Do the math and use your own judgement and common sense.
