Little correction.
You said: "..When i free-dive, and I get starved
for O2.."
It's actually a CO2 level in your body that
forces you to breathe, not lack of O2. There's
still plenty of oxygen in the air we exhale (like
18% if I remember the number right). If you could
just get rid of CO2 from your lungs, you wouldn't
feel that "I wanna air NOW!!" thing :) for quite
some time.
