Beijing subway travel during rush hour is a numbing experience.  Within two weeks of morning rush hour travel I too have become personally desensitized to the discomforts of the train.  It is a torture you endure until you are released onto your destination.  I sense from the running of many on the street that the discomforts of the train are only the beginning of the daily grind and that the race to work may indicate indignant bosses carefully watching the clock.
