It's crowded in here!

     Imagine waking up 30 minutes late for school and your mom yells, "Get up, you're late!" Then in a panic you jump into the shower, put on fresh clothes, and rush to the train station, but when you arrive you realize that you could have probably skipped your shower that morning because the train is already full. I know you're saying to yourself, "why would the train being full cause a person to wonder why they even bothered taking a shower?" Well being late for a train in Japan during rush hour means being pushed into an already crowded train by two or three people until you fit into that living suitcase. The train is packed so tight that a person can feel the sweat rolling down their backs and strangers breathing on your necks, as the train roars down the track. The population density in Japan is insane, but this is their way of living in this country, even if it is extreme to us.
Do you believe that Americans would be mentally capable of adjusting to such an extreme way of living?
