My sweetie and I discuss this all the time. She can be freezing at 75 while I am melting. Really! She is a desert rat and needs her heat. I am a weenie who likes it between 68 and 70 only. Less and I am cold, more and I am hot. And I use dogs as bedwarmers.
Summer in Texas is gonna be...interesting.
I think her cold-bloodedness may be related to having a large area of skin to dissipate heat but it's barely even a theory...women are tough to figure out! Especially THIS one. Talk about blowing hot and cold....
