　　　Why do people drink too much, eat too much, smoke cigarettes or take drugs? What's to blame for all the bad behavior? Most people would say that, while these self-destructive (自我毁灭的) acts can have many root causes, they all have one obvious thing in common: they are all examples of failures of self-control, lacking the will power to resist them.

　　　According to a recent study, however, if you really think about it, something about that simple answer doesn't quite make sense. In fact, it turns out that sometimes it's having will power that really gets you into trouble.

　　　Think back to the time you took your very first sip of beer. Disgusting, wasn't it? When my father gave me my first taste of beer as a teenager, I wondered why anyone would voluntarily drink it. And smoking? No one enjoys their first cigarette - it tastes awful. So even though smoking, and drinking alcohol or coffee, can become temptation (诱惑) you need will power to resist, they never, ever start out that way.

Just getting past those first horrible experiences actually requires a lot of self-control. Ironically (讽刺的是), only those who can control themselves well, rather than give in to them, can ever come to some day develop a "taste" for Budweiser beer, Marlboro cigarettes, or dark-roasted Starbucks coffee. We do it for social acceptance. We force ourselves to consume alcohol, cigarettes, coffee and even illegal drugs, in order to seem experienced, grown-up, and cool.
