Stand tall!
昂首站立
Think of yourself as a puppet with a string coming out of the top of your head. Now imagine that someone's pulling on that string, causing you to sit (or stand) straight and hold your head high, with your chin tucked in slightly. You'll take 10 years off.
把自己想象成是一個牽線木偶,頭上有一根線牽著。現在想象有一個人拉著那根線,迫使你坐直了(或站直了),把頭高高地揚起。這時候你的下巴會微微收縮,看起來就像年輕了10歲。
