Pain is the price we pay for being alive. We don't need to engage in self-destructive behavior to experience pain in our lives, in fact a lot of self-destructive behavior like overdosing on pain killers
is an attempt to escape from all the pains of ordinary life. Exercise is painful but it makes you stronger as long as you don't push yourself so hard you have a heart attack which you can also get by not doing anything more painful than being a couch potato, People watch horror movies to
prepare their psychological defenses for dealing with all the horrors we see everyday on the six o'clock news. Any obsession can be harmful to ourselves or others if we take it to the point where it blocks out everything else which is why we should try to connect with people who don't share our fascinations so they can give us reality checks when we start heading off the deep end. Every Sherlock Holmes needs a Doctor Watson. Being able to deal with pain better than most people
gives us an advantage in many situations but that gift shouldn't be wasted by putting yourself
in danger of serious injuries for no reason which I personally think you should be spanked for.
