Improvement! A big thirty-five minutes out in the elements, and my skin did not slough off, nor was there any blackening of my extremities. The temperature is a balmy minus 14 which is ten degrees warmer than it was yesterday. Still, it was a short walk. Longer tomorrow. Longer still on Friday, as the temperature rises.
It was very cheering to see the sun, even if it was only for a few minutes. I should really leave my office at noon.
