When temperatures hit the teens, running is better than walking. This morning I skittered to my office, shortening the seven-minute stroll to less than five. The sun wasn’t up yet and a dreary light filled the void. Cars belched clouds of visible exhaust and the few commuters I passed kept their heads burrowed in their scarves.

I tried to keep it loose but when I’m cold my shoulders bunch and my grip tightens. I cinch in my coat, turn up my collar and dash down the sidewalk. This is not the way to deal with winter, I know. It’s easier when you relax. But today I’m moving quickly, still trying to beat the cold by moving through it as fast as possible.
