I've always been curious about addictions. It can be a slippery slope where you try something (alcohol, drugs, jumping out of a perfectly good airplane) and it brings on a euphoria that's hard to beat. But then you get used to that 'high' and it becomes normal, so you move onto something bigger and so on until you need that addiction satisfied so you just feel normal. What LEADS a person to that end though? Is it boredom, disappointment, pain, peer pressure or what? Maybe having never actually been an addict I can't understand, but I'd be interested in everyone's opinions on it none the less. Also, why are drugs and alcohol "bad addictions" while bungee jumping and hiking for hours "good addictions"?
