Cold means quite a different thing to different people from different regions. How many times have you heard someone state they are 'freezing' when you feel the temp. is just fine?
Growing up in OC I remember it dipping down into the 50's and people bundling up. Now in the Pacific North West. 50's is nothing, when it gets to the 40's I feel cold and the 30's I need a jacket and so on as the mercury dips lower and lower.
When it has been in the 30's for a good bit a wam day of 50 degrees allows you to go outside and bask a bit. In the early sprint 60 degrees means shorts and T-shirts.
This isnt a new discovery or anything. Just something I find interesting when I chat with my OC friends. I first noted that where you lived determines cold from Delta Joe. It was a brisk day in Pasadena in the mid 50's and he was in cutoffs and a t-shirt. At that time it was cold to me but not to Joe.
He had come from Alaska.
I have often wondered about someone who transitions from extreme conditions. Like from Edmonton to Atlanta...
