專家說，笑容有19種不同的類型。換句話說，人們的笑容會根據(jù)特定的環(huán)境而有所不同，比如出于禮貌的、快樂的、理解的、仁慈的等等。

看看下面這些由攝影師們捕捉的畫面，嘗試著區(qū)分不同類型的笑容看看。坦白說，編排這組照片時，我們很難界定每種特定的笑容。我們唯一得到的結(jié)論是這些笑容都是真誠的，絕不做作。真誠，以眼神傳達，用言語詮釋，絲毫不會有虛假。而且科學依據(jù)也表明人們能夠憑直覺區(qū)分真假笑容。

笑的現(xiàn)象的確應該加入世界吉尼斯記錄。笑是人們與生俱來的本能，不需要學習。由于荷爾蒙釋放，壓力消除，笑會令人健康快樂。事實上，笑容益處多多——據(jù)統(tǒng)計，常笑的人會有更豐厚的收入，笑會使女人更活力迷人。經(jīng)科學證明，笑容能“傳染”，我們應將這一理念植入心底?？赐晗旅孢@組作品，相信你也一定會被感染的。
