Body Language

Hello!
How are you? Recently, Japan becomes little bit cold. I feel winter is coming soon.
Anyway, I will talk about a body language because I learned about it in my class. There are a lot of body languages both of Japan and the U.S. Some one has almost same meaning, but other one has big different meaning. I am really interested about the differences of body languages. For example, when a person play his hair, it means "vanity" in the western countries. However, I have not think such a meaning before as a Japanese. In addition, I did not know a person sits and hugging with his arm by himself means "shyness". I sometimes do this gesture, but I have never wanted to show I am shy.
I want to know more interesting body languages!
Please tell me about body language that you use frequently.
