I like the cold, much easier to get warm then it is to cool down, especially when you work in a shop with 2 ovens pumping out 260 degrees of heat, sure I could wear less but if I started going to work in nothing but my boxers I would be in big trouble... plus I would have to deal with all the women lusting after my semi naked body/smug

On a side note if you want to know real cold, try wearing riding leathers and going on a long journey on a bike, THAT will bring new meaning to the word cold.
