I probably ought to stay out of this one since their are people out there that know a LOT more than I do, but... If you have that 'will of iron', you will - in theory - be able to hold your breath a lot longer at depth. Trouble is, it's not a simple equation. You'd really be screwing up your blood chemistry by doing this, and that may affect other body systems (especially the brain). And the problem has never been "holding your breath at depth" but managing to keep from blacking out on the way back up to the surface as the O2 becomes scarce. If you were, say, resting on the bottom at 130', were well weighted, no current, and you tried something like this, you may find you _can_ hold your breath a long time, but I certainly would never attempt a stunt like that! Even with an experienced safety diver, I couldn't control everything that might happen. Didn't someone once say that the idle mind is the Devil's playground? Looks to me like you're tap dancing at the top of the slide. ;-) -- Robert -------------------------------------------- E-mail: RLaird@pe*.co* (Robert Laird) 12/13/94 14:27:43
