lol @ hand to hand combat in water....good luck with that haha.
I teach these kids skills with scuba that they can apply to all aspects of their life.
The giant stride entry? You fall the way you look. You'll belly flop if you look down. If you are involving yourself in bad shit, you're life is going to go a bad direction.
Stop, breath, think. Applies in scuba, applies in life. Something starts to slip away from you, you don't panic, you don't give in....you stop your natural urge to seek the quickest and most likely least effective solution, you take a decent number of breaths to slow everything down, you think it out. Then act.
