Good points. Any sport taken to the highest level is not simultaneously optimal for longevity.

I've been involved in the bodybuilding community for a few years and it's quite an interesting one. Plenty of people will continuously tell people that they are "100% natural" without anyone asking and they are usually the ones who are using tons of anabolics. It was also fascinating to learn about how athletes of other sports get away with anabolic use using some very clever methods. Nobody in professional sports are truly clean.

Also, Olympic lifting is very very different from bodybuilding. If you do a snatch next to a typical bodybuilder, he will act like you're completely insane and tell you that "you're gonna snap your shit up". Your body adapts to take on the ideal form for your particular sport within the constraints of your genetics.

I find that Asia is becoming increasingly westernized and that America is becoming increasingly easternized. There are tons of gyms in China now and it's quite easy to get your hands on anabolics there. Also, I don't believe there's a real difference between internal vs. external martial arts. Bruce Lee and Joe Rogan had both said some great stuff regarding this topic. It basically comes down to that you have to do what works or you'd your ass handed to you in a real fight, which can be seen as a form of scientific experimentation to figure out the optimal form.

As for the philosophy of bodybuilding, I highly recommend watching Frank Yang's videos:

These are just a few. He's one of the most entertaining and thought provoking thinkers I've ever encountered.
