I don't think I've acclimated to cold winter weather nearly as well as you have. If I had never started wearing layers (long underwear plus my pants over top, tank top, t-shirt, hoodie, etc) I might have, but I'm still not used to being in the freezers with the cold fans blowing. Anytime I leave my department I'm instantly dying from the heat, but winter weather is still cold for me.  The worst part is the dry hands. I don't like wearing gloves because with them on I drop everything, and I'm always losing boxcutters so I just stopped using them and break open boxes with my hands or rip the tape off with my fingernails. Can't do that with gloves on.
