Winter in New York is hard. I've been told that the body doesn't produce as much vitamin D, which causes all sorts of problems. I look back to this picture, taken only a few months ago, underground, in the subway, and I can see how much happier and healthier I was. It's a constant struggle. Exercise is supposed to help, especially cardio, but that's really difficult to do in the winter. It takes a lot of effort to get to the gym and then you come home wet and cold, and complaining. Like now.
