A change of pace

My lifestyle is much too sedentary.  I’ve decided that to combat this I will involve various new things in my daily doings that will help to burn extra calories and tighten my physique.  First, instead of just standing in the subway car on my way to work or wherever I will pace.  I will do this as unobtrusively as I possibly can, as the cars can at times be crowded, by pacing into whatever open space is available, the entire length of the wagon if possible.  If the wagon is overpacked then I will have to just stay in one place and spin my body round.  Hopefully this will catch on, the entire city will be enjoying a much higher quality of life with an increased level of hustle and bustle, mostly bustle.
