In-depth

info hard to come by in land-locked place where I live.
Tyler, did you get your 6 hours??? OK. Being silly here.
At least ask Eric Fatah if he got his 30 minutes? I really believe it's possible--under the right circumstances. A Hatha Yogi did a 22. If this is considered a dangerous thought--forget it.
Why this stuff fascinates me so since I was a kid, I can't say--EXCEPT: Breath-hold divers are born, not made.
