1. Look at the person’s eyes. The face itself, and specifically the eyes, contain the window not just to the soul, but to good face memory. The eyes are a feature of a person least likely to vary over time or under different circumstances. Apart from the aging process, which adds a few wrinkles here and there, people’s eyes don’t really change. By focusing on this nonvarying piece of anatomy, you'll be less tricked by changes in hair length or color, clothing, and even body shape and height.

1. 注视一个人的眼睛。脸尤其是眼睛不仅是一个人心灵的窗口，还是面部记忆的窗口。无论在任何情况下，眼睛是一个人最不可能随时间变迁而改变的特征。除了会因岁月而留下一些皱纹外，人的眼睛实际上是不会变化的。只要留意这一不变的特征，你很少会被头发长短与颜色、着装甚至是体型及身高的等的变化而蒙骗。
