Breath holding techniques and lung expansion

I'm convinced that doing extended breath-holding / apnea swimming / training / skindiving over a long period of time kills brain cells and makes you dumb(er)

 

Yes it does! Talk to any longtime SCUBA diver, they are so wacked they make fiberglass dudes seem coherent. Just reading this thread ( I can freedive 50 plus feet easy cause that's all I did as a kid ) makes me short of breath. I have trouble breathing after reading some of this stuff. Great informative links, but damn. If it takes that much work, give it up before you go all fuzzy wuzzy down there.

Does the name Jay Moriarity ring a bell? DING DING DING! Wake up!!! Ooops, too late.........blub blub blub...
