So whenever you want to look great and competent, reduce your stress or improve your marriage, or feel as if you just had a whole stack of high-quality chocolate without incurring the caloric cost, or as if you found 25 grand in a pocket of an old jacket you hadn't worn for ages, or whenever you want to tap into a superpower that will help you and everyone around you live a longer, healthier, happier life,
如果你希望自己看起来更棒更有能力 减轻压力 或改善你的婚姻 或者感受吃了一大推巧克力后的快感－－ 而不用担心热量过多－－ 或体会你在多年未穿过的外套口袋里 摸出了25万元时的狂喜 还有你想要得到一些超能力的时候 微笑能够帮助你以及身边所有人 活得更长，更健康，更幸福
