Didn't he mean that you'd only attempt this if the air suddenly ran out or there was some pressing emergency that would prevent a controlled ascent (serious failure of the dive chamber perhaps)? 1. In case of emergency, always follow the bubbles The only problem with the slow ascent mantra is when the air runs out while you're underwater. You hear a click as something shuts behind your head signaling there’s no more air available and then you try your very hardest not to panic. Human instinct tells you to get to the surface as quick as possible – but that could result in a bad case of The Bends. The golden rule is to follow the bubbles. So you'd hope that by the time you reach the surface your support crew would get you back under pressure again to dissolve gas bubbles back into your body fluids, and hopefully you survive.
