　　Jason's mother sat him down at the dinner table one Saturday afternoon to a feast he could not believe. In front of him were his three favourite desserts.

　　As Jason wondered what he had done to deserve them, his mother spoke, "Son, you see your favourite desserts, right？" Jason nodded.

　　His mother continued. "Now, I have some good news and some bad news for you. And then you get to make a decision. The good news is that you get to choose one of these three desserts to eat."

　　So, that was it? He could only eat one.

　　"The bad news is that I have put poison(毒药) in one of the three desserts，"Jason's mother said. "The poison is so poisonous that it will kill you in a matter of minutes. It will be painful and there is no antidote(解药). If you don't die immediately, you will know that you have chosen well."

　　Jason's mouth dropped open. "You're joking, right？"

　　"No, son，" his mother replied. "I'm serious. Now, which dessert do you choose? You have ten seconds."

　　"This is crazy，" shouted Jason. "I don't need ten seconds! Only a fool would eat any of the desserts now that you've said eating one may kill him."

　　Jason's mother nodded in agreement. "That's right，"she said. "Only a fool would take a one­in­three chance of eating something that could kill him, even if it tasted really great." Then his mother lifted a package of cigarettes and put them on the table. "Tell me then，" she continued, "why would a teenager ever smoke one of these terrible things when the chance of dying from smoking­related illness is one in three？"

　　Jason's face turned red. This has become one of the most important lessons for him. He would never choose a poisonous cake as well as a cigarette.
