Burning calories

Today was the first day of the Golden week. I went to a gym in Kabuki-cho with my friend. We spent 6 housrs there for 3 studio probrams, machine exercises, swiming, having a bath and sauna. I'm sure we burnt off a lot of calories but we also took more calories afterwards at a Yaki-niku (Korean-style barbecue) restaurant...
The gym was big and well-equipped one in Kabuki-cho.
It was strange feeling to come out to unhealthy city after doing something healthy. Doing exercise in a building is not really healthy though.
I never feel confortable walking Kabuki-cho but I found that it's really strange place you hardly ever found any other place in the world. A man is selling fresh seafood in front of the restaurant and next to it, there is a entrance to a dirty place. There is a hospital next to a "Love Hotel"...
