I am so cold. So uncomfortably cold.
I use to laugh at the cold. Well, not anymore. After losing a significant amount of bodyfat, I now feel the cold more acutely. A lot less insulation, you know.
I wasn't fat before, and I certainly wasn't a couch potato by any means. (You could say that I agree with this philosophy.) I also used to quietly scoff at people who complained about the cold. Well, not anymore. (To be fair, most of those people were fatter than I was. However, I also have to remember that some folks will just tend to be more temperature-sensitive.)
