I don’t get it, in my experience it sucks no matter how short or long you do it. Like, if I put my arm into a 100°C oven for longer and longer it doesn’t suddenly start feeling good, it’s the same uncomfortable-to-stressful experience every time (and at some point it causes physical damage). Obviously with exercise your body can build up muscles to make the experience less awful, but it doesn’t prevent it from being a purely stressful one, both mentally and physically (and at some point all the constant stress causes mental damage). Even after weeks there’s no difference, except that I was so stressed I lashed out against everything and everyone.

I do not understand (on a subjectice level) how this can be any different for others. I’ve read about dopamine being supposed to be released, and it truly has to be copious amounts to block all the stress signals and somehow turn it into something positive. Basically the only sane explanations there is to me why people would do this to themselves are either external necessities or the desire to get high on built-in drugs which only works for some people (who then believe it’s that way for everyone).
