Boss, your topic is a little bit different than the TS'--kanang imo, "Bends" man na, the effect of rapidly ascending from depth to surface, causing nitrogen in your bloodstream to form bubbles and thus affecting circulation and causing nitrogen drunken sensation in your brain. The reason why freedivers don't get the bends is because they are holding their breath, and thus they are not introducing compressed air into their bloodstream--they only get the air from their lungs, which is still at surface air pressure, which is why you really need strong diaphragm muscles for freediving, apart from the ability for apnea.
