15种肢体语言解读 学会这些你也懂“读心术”

3. 眼角没有皱纹的笑容可能是假笑

If someone's trying to look happy but really isn't, you won't see the wrinkles.
如果有人试图表现出开心的样子，但并不是发自内心的高兴，那么你是看不见对方的笑纹的。

More recently, a study from Northeastern University researchers found that people could do a pretty good job of faking a Duchenne smile, even when they weren't feeling especially happy.
最近，美国东北大学的一项研究发现，人们即使并没有感到特别开心，也能伪装出完美的假笑。

It seems safe to say that if the crinkles aren't there, the person's probably not genuinely happy. But just because the crinkles are there doesn't necessarily mean they're elated.
所以比较保险的说法是，没有皱纹的笑容证明一个人可能不是真正的快乐。但仅仅因为笑出皱纹，也不能确定一个人真的很开心。
