houses, food, and cars are all much smaller in Germany, and Europe in general. the first time I went to Iceland, one of the first things I noticed was that all the food portions were WAYYY smaller. Your typical can of soda is about 8 ounces (it's in ml, and I don't remember the number, but it looked to be about 8 oz). One of the other first things I noticed is that everyone is way more fit than Americans. We eat too much, so we're a bunch of fatasses, so we need big cars and big houses to contain our fat, slovenly selves.
