It ain’ no thang.
What I got for Christmas was a headcold and a driveway full of snow. So I dressed a little warmer than I might have otherwise and went out into the remains of a snowstorm (and howling wind) anyway and shoveled the driveway, the steps and the walkways to the house.
After the initial shock to the system (you’re never dressed quite warmly enough) the activity is enough to keep you warm, and it’s nice to know that your body can still respond and that you can shovel all of that, in time. I have to take more breaks than I used to, but I’m also less likely to be overwhelmed by it: it’s just going to take time and effort. And a good heart, of course. (If you’re not completely out of shape, the shoveling is a pretty fair exercise, too.)
Of course, my back isn’t speaking to me today, but other than that… not so bad.
