"The body thinks it’s on fire, so it unleashes a wave of endorphins to help quell the burning. You start to feel something akin to a runner’s high. The sharp stinging pain will subside, but the rush — and subsequent sense of tranquility — lasts a bit longer."

I've always liked spicy food but not to the point they cause physical discomfort this just seems like a waste of good spices to me, a far more economical solution would be to just eat a piece of conservatively spiced chicken then have your buddy kick You in the balls.
