I’m giving a lot of things up lately. New this week: My car. Today is the first day I walked to work. It took longer than I expected, 52 minutes door to door. Perhaps there is a shorter route. I breathed a lot of noxious fumes and I have a headache now from that. Next I’ll take the bus. Then find a cheap bike. It was fun walking past the $3/gal gas signs. Walking for a few hours per day is also pretty good exercise.
