Why would a being use something that inheritantly harms them (drink, smoke, drug, excess)... but can bypass their built in survival instincts and do it anyway, despite knowing the risks... is dopamine/chemical release that important that one can even harm ones whole organism?<br><br>I'd like to know the science of when a person is able or willing to take things that far... from risky pursuits such as parachuting, to more subtle things like drinking or smoking etc...<br><br>Input welcome, from one lost soul to any other!? 🙏🏻
