Considering we'll occasionally ride the subway one stop too far just to get out at the stop that has an escalator, we're now wonderigng if we're obese. We're not quite there yet, but if you have to be obese to ride the escalator at this place, we'd gladly stuff some pillows under our shirt in order to avoid stairs at every opportunity. You can be skinny and still not want to exert any effort, you know. It's called depression.
