It's interesting how so many people will balk at taking an illegal drug because they "don't want to risk brain damage", and yet will think nothing of driving or riding in a car and risking both brain damage and death nearly every day.
Mountain climbing, rock climbing, skydiving, scuba diving, and even just walking across the street all risk serious bodily injury, brain injury, and death. Yet most people won't freak out if you choose to engage in one of these activities.
But if you dare to swallow a pill every now and then, you're treated as a reckless, immoral madman.
