56-y-o. Commuted years ago in seminary in the Twin Cities during the five years when I didn't have a car. Then there was getting married, moves, kids, etc. I continued to ride, but put commuting on the shelf. I was preparing for a summer sabbatical three years ago that started with a five week canoe trip in MN and Canada. A friend in my congregation mentioned one of his favorite quotes from running guru George Sheehan: "First, be a good animal." After the sabbatical I started cycle commuting again so that I could use my body not just for play or exercise or enjoyment. I get cranky now when I have an offsite meeting or hospital call that requires me to drive in. Being a good animal grounds me in a way that I need to be grounded.
