Macho, dare-devil behavior is common. As is self-destructive behavior. These days plenty of folks like to try things, just to say that they did. Most don’t believe that they will be hurt. Most think they are one of the very few that can go through the experience and brag about it.
A parallel might be those that sign up to take a flight in a supersonic jet fighter. The pilots are instructed to make the ride a vomit inducing puke fest. The rides cost $5k on up. People do it and tell their friends that they did it, and almost all lose their lunch into the oxygen mask. Fun? For some, or at least they think it might be fun.
For some folks, they just want to feel something, anything, and seek extreme thrills, or extreme eats in their search. The adrenaline junkies are on one side of the spectrum, and the sensitive easily upset folks are on the other. In the vast middle are the average folks with average temperaments and average tastes.
