I have always thought that cold was relative. For example, in the fall when it gets down to 60, I start wearing a jacket or a sweater. In the spring/end of winter, when it gets up to 60, I wear short sleeves. It's all about comparison.
My parents live in Detroit, so they get lots of lovely snow, and my dad just sent me this chain e-mail that shows that cold is not only about comparison, but about what you're used to. I hope it gives you some chuckles like it did me.
