By the time I leave work I check my pedometer. I make sure I see more than 5 miles a day. It hasn't been a problem since I work in a place with a huge campus of 5 buildings. I park far away, I enter the wrong door, I take the long way to the bathroom. I walk to the next building for lunch and try to get 2 miles after lunch before the afternoon meetings. If by the end of the day I need to pull in a mile, I walk the "loop road" which is 1.5 miles. It all adds up. I walk slow because of the pain mentioned in previous posts... but I do walk about 2.5 miles/hour. The 15 minutes here, 10 minutes there and 40-60 minutes at lunch all add up at the end of the day. Therefore, I've decided that I am now a meander-thal, since I take meandering paths to get my daily activities done.
Funny though, my knuckles no longer drag.
