There's an angle to staying warm that you could have mentioned, and it is that many animals don't maintain their extremities at "body temperature." Many mammals and birds in cold climates have heat exchangers called rete mirabile at the base of their limbs that warm the blood returning from the extremity, thus keeping the heat in the body. The reduction of heat loss through the large surface-to-volume ratio of the extremities is an enormous energetic benefit. Cold hands saves body heat and is the cost of not having huge mittens. But hey, I live in Florida. We don't need no stinkin' mittens!
Love this one-being a life-long Seattleite, I am totally with you about the heat...
I appreciate the recordings very much. I walk in the morning and play them through my hearing aids. Very fun!!
Thanks for letting me know!
Love this story!!! (I'll stick to my flannel shirts for now...) Cheers!
