Emailed with an "only 82" year-old friend this morning. He had just come back from a 3-mile run in the snow. He said that running with snow falling is exhilarating.
I remember doing that, back before I concluded that road-running was a bad idea. It truly is more fun to run in weather.
So he is 82 and out running, and I am much younger and doing HIIT on a stupid treadmill.
