Lots of things make us look old, but nothing does it more than a stooped posture. Think about it. Haven’t you looked at someone walking, hunched over, and felt sorry for that ‘old’ person? It’s so common to think of age and poor posture together, that if someone is standing upright, you must assume they are younger. It’s the same with weight, a bad posture makes you look out of shape. Plus, when you are bent over, doesn’t your stomach look gross? Isn’t it protruding, compared to standing upright? Also, a good posture makes you look more confident— there’s 10 years younger right there!
