Culture Shock I'm OK.

A lot of people think or expect America, Americans thier culture.
Also me too, but When I go to here I felt culture shock in america.
first, there is a lot of people too fat and obese child.
American peoples eating too salt, too fat and a lot of instant food.
So, American peoples become too fat and ugly.
Second, In Korea I can drink a beer, alcool and whisky in the street.
But In USA I can't drink a any alcools.
But! There is a exception in UAS in Las Vegas.
I know there is a lot of country in the world.
So, a lot of culture in the world.
We can understand possible their cultures.
