描述: it's no secret that brains are plastic. they can be molded, shaped, influenced & changed throughout our entire lifetimes. but maybe you didn't know that plasticity is competitive. if certain functions aren't used for a long time, other mental operations will take over that 'cortical real estate'. what functions are you neglecting when you jerk off for hours like this? are you priming your social skills right now? honing your sexual prowess? excelling academically? you're literally making yourself more and more of a stroke puppet with each touch, with each jerk session, and yet you won’t stop. it’s hard to now. your brain doesn’t know what to do with itself. it takes so much mental energy to redirect your attention now, to operate on those rusty old pathways...they might as well crumble altogether...
