When I was in high school, going to the gym was fun. The idea was to work out with friends, but now it's like you described: they only go to take pictures to sell you the idea that they're healthy, fitness people. It's all about selling you a false image of life.

Not only that, there's the danger of being called a stalker or rapist for sitting on a machine, looking at the wall to rest for a while, and then a girl walks through the wall, sees you, turns around, and accuses you of being there all alone, even though you were there first, just to stalk her and stare at her butt. That happened to me once. Luckily, another girl saw everything, went up to her, and yelled, "Shut up, bitch, we want to work out!" That got rid of the troublemaker, but the feeling of dread stayed. From that day on, I never went back to a gym! Boom, an anecdote just popped up without me even realizing it.
