Yes Helen, right on! I obviously want to feel good and look okay in my clothes, but this is really about healthy vitality.

I do walk outside quite a lot, but with this cold snap we've been having, and my requirement to work at home, I have been cocooning quite successfully. Tomorrow I venture back into the real world--10 minutes on foot to the subway, 5 minutes to the office, often out shopping at lunch on foot, and reverse to go home. I rarely drive to work (about twice a month), and we really only use the car once a week, especially in the winter, to do our grocery shopping. David walks to work most mornings, about a 20-25 minute walk.
