This numb-skull had to re-learn a lesson about the importance of keeping my hands warm. The other day my son and I were working outside. I normally wear warm gloves, but somehow didn't think I needed them that day - (it was just above freezing outside) After 30 minutes or so my hands started to tingle. I thought about getting the gloves, but I was in the flow and didn't want to stop. Sometime later, my fingers started to burn and I no longer had any useful manual dexterity. At that point I went back inside and warmed up. I thought to myself...What if I had been in a wilderness or survival situation? There was no way I could have started a fire easily with these numb hands. Stupid me. Lesson re-learned.
