Ever heard the word 'identity' and 'identity crisis'?
Not saying personal hygie is not important, but when it makes you over sensitive about your self-image, and when you make *extra* effort just to feel 'you are the same as another group'. You are experiencing identity lost.
As someone stays (not want to stay). I'm always proud to live a very Chinese life. Yes, I volunteer in my kids school, I participate in community services, I do my hair/facial etc. But I don't know about a thing about sports and feel perfectly fine in saying so. -- I live my life and make my choices because who I am, not by how other people judges me.
