-23 right now Chris. Geez it was enough work sleeping in my warm bed and listening to my oil burner cycle and hope it continues to do so. I do have outside chores and had to make an emergency plan with my wife just for that last night. It really is amazing the fine line of safety and you really can feel the difference between -5 and -23. I just came in from my morning 5 minute porch stand in my skivvies and my knit 'smoking jacket'; absolutely amazing how quickly I felt the blood drain from my brain as my body reacted to the cold and very quick alternation between hands in pockets to prevent flash freeze.
Yesterday morning we woke up to an 1" of puffy snow and I had hoped I could largely stay inside all day, but no. Our driveway can't tolerate anything less than near perfection due to its steepness, and with retirement I can find time to shovel light amounts- always pure pleasure. So just before noon with a temperature that started at -5 and dropped to -7 over an hour and 40 minutes for the task, instead of sitting nearly motionless on a tractor to push snow back and forth between the snowbanks, I shoveled.
Not the first time in similar or lower temperatures, and I do recommend it as practice or a reality check for those who choose to live and may have the need to function in such conditions. Since my activity was aerobic and required moisture management and available calories, I could pay very close attention to the balance of exertion and sweat production and try to adjust with each physical motion. I could also closely feel the level of available calories and hydration towards available strength and the needle dipping in me, and the effects on my brain- an onset of a bit of a loopy feeling. And it was not even that bad yet. I was reminded yesterday while out there of an account I had read from some of the rescuers in the Tinkham/Haas case (I think it was this case), where the rescuers described having to move like they were astronauts on the moon. Very slow and deliberative as they attempted to manage the moisture levels they were producing.
