I have found some interesting differences between many countries including the US and my country, Japan  by meeting and learning from people from countries all over the world since I came here in the US.  Especially on this page, I picked up the difference of the counsciousness for the national anthem and frag between the US and my country.  Because of my poor reserch, the information on this page might not be correct.  If so or you know more, please send e-mail to me.
