专家说，笑容有19种不同的类型。换句话说，人们的笑容会根据特定的环境而有所不同，比如出于礼貌的、快乐的、理解的、仁慈的等等。
看看下面这些由摄影师们捕捉的画面，尝试着区分不同类型的笑容看看。坦白说，编排这组照片时，我们很难界定每种特定的笑容。我们唯一得到的结论是这些笑容都是真诚的，绝不做作。真诚，以眼神传达，用言语诠释，丝毫不会有虚假。而且科学依据也表明人们能够凭直觉区分真假笑容。
笑的现象的确应该加入世界吉尼斯记录。笑是人们与生俱来的本能，不需要学习。由于荷尔蒙释放，压力消除，笑会令人健康快乐。事实上，笑容益处多多——据统计，常笑的人会有更丰厚的收入，笑会使女人更活力迷人。经科学证明，笑容能“传染”，我们应将这一理念植入心底。看完下面这组作品，相信你也一定会被感染的。
