Yeah it's been crazy, up to 30 degrees temp difference between days! 50s one day, 20s next day, then back o 40s, then down to 20F again.... Nuts. I haven't been getting sick as much as used to since I started riding my bike regularly. I really believe I caught something on the subway last Friday. So far no one at work is sick. Lots of folks were coughing and sneezing on the train. I took the subway because the temperatures dropped from low 50s to low 20s again overnight and I was just too burnt out mentally to deal with that kind of cold in the morning. I'm really tired of Winter this year. So I bundled up and took the subway. At least that would explain the headache all day yesterday. I think I'll stay home actually.
