I'm more asking about underlying reasons of laziness and lack of joy in moving. That aside, I miss bicycling to work.  Moved from the country side to a large city (without fucking shoulders or side walks - in the suburbs) and would probably end up dead in a week if I didn't do the annoying bicyclist thing of getting a stick that fucks up a car if they don't stay so far away from me.  I really hate those guys though, so it's more just walking when I can.
