Where someone is from is not very significant...what they are acclimatized to is..

I'm from Ohio, but after first year and half in military spent in: South Carolina, North Carolina, Memphis, and Okinawa...my family would all laugh at me for being a little B about the cold, when I'd go home to visit and it wasn't even winter.

Acclimatization is a real medically/scientifically recognized thing, not something we just made up on UHND to frett about oppopponents.
