General Discussion - What if there was a Chinese Version of "Ask Amber, guide to Western Culture"?

So I was imagining, what if there was a Chinese Version of "Ask Amber", all in Chinese of course.  What types of questions might Chinese people write in to learn more about Western culture.  So I thought I would get this idea rolling with a few actual questions that I have gotten from some of my Chinese acquaintances:

     Why do you apologize so often?

     Do people eat vegetables in your country?

     Why do Americans smile so much? 

     If you are American, why aren't you fat?

What other questions might Chinese want to ask about western culture?
