The Brazilian TV show Fantastico asked the viewers what is the best decision to make when an ocean current drags you during scuba diving and you have no more oxygen left in you compressed air cylinder. The options to choose from were: a) follow the fish, b) swim for the open sea or c) swim with the current.
Most of the people answered option A. It is the wrong one because our biological system is not the same as the fish and we cannot handle what they can.
If you want to survive, the correct answer is option B. Why: when you get away from the barrier reef and swim, your body will naturally put itself in an angle of 45º leading you towards the surface. Stop on the last 4.5 meters before reaching the surface because of the pressure.
