winter light midmorning, a cold day

Sometimes I wonder how people lived before thermometers. How did you know what to wear outdoors? Today is in the 20s. I've left this morning's run for this afternoon. I needed a break from the routine. It's very hard to get up early in the winter and run in the dark. The cold doesn't bother me running in the winter, but what does bother me most about December has nothing to do with weather but with the way the year so quickly just peters out. My work is measured in months and years and not days so the turn of the year is significant.
