Because it’s tempting as heck. You’re on vacation, the water is turquoise, and a guy named Kai says, “Just breathe, man, it’s easy.” Your brain goes, “I have lungs, I breathe daily—how hard can it be?” Very hard, actually. It’s like saying “I can fly a plane because I have arms and wings don’t exist.”
Also, the gear makes you feel invincible. A heavy tank, a regulator that hisses like a sci-fi prop, and a mask that gives you bug eyes. You look like a deep-sea cyborg. But that cyborg has no manual and probably forgot to check its O-ring.
The Worst “But It Worked” Story
I once met a guy in Belize who “learned” diving by watching a VHS tape from 1998. He borrowed gear from a friend and went down to 25 meters. He surfaced with a nosebleed and a splitting headache but said it was “fine.” Later, a doctor told him he had a mild air embolism—tiny bubbles in his brain. His takeaway? “I’ll bring a decongestant next time.” That man is now a surfing instructor. Survival does not equal skill.
