Raptures of the Deep
Nitrogen narcosis is also known as raptures of the deep (“l’ivresse des grandes profondeurs,” as Jacques Cousteau put it), or the Martini effect. It is a consciousness-altering condition that affects divers at certain depths. While a diver is affected, she may feel euphoric and see things that are not really there. Like nitrogen narcosis, shark movies are great fun but sometimes they are not very good for you.
