And on the topic of Japan ...

Another thing I noticed during my time living in Japan was that they eat slower. Why? In general, I think, because they eat with chopsticks. Don't get me wrong, you can eat hella-fast with chopsticks if you want to, but usually you will eat slower. I am pretty good with chopsticks and I eat slower when I eat with them. Taking time when you eat is a great way to not overeat. Your body appreciates it, too.
