Some things...

Some things I noticed so far:

Eating
Everybody here (at least in the Mensa) eats incredibly fast! And Japanese doctors are the fastest eaters I have ever seen live (I am not sure if they swallow at all). Lunch normaly takes about 20 min. incl. 10 min. walk to the Mensa and back, buying the food and taking a seat. I am always last (I know, I am a slow eater, but maaan, they are fast). This might be one of their secrets of productivity. What ever, I stated to eat less during lunch until I am (at least nearly) as fast as they are. Further food is good, relativly cheap (I bought sushi bento, a luchbox with sushi, for around 2,20 Euro. In Germany this would have cost me at least 6 Euros), but different.

People
Everybody I have met so far was really nice and helpful even though their english-skills are often close to 0. Furthermore, women support the shoe-industry by not lifting their feet when they walk, creating an interessting sound while they walk.

Later more :)
