Fourth Seven-day challenge

My next 7 day challenge is to take the stairs if I am going one flight up or two flights down. Before I had the chiari surgery, I was compulsive about taking the stairs thanks to a tragic elevator accident at college that killed a coworker. I was terrified of elevators and would walk the fourteen flights to my dorm frequently. Once I had the craniotomy in graduate school, I would get a headache and become lightheaded while walking up and down the stairs. You burn about 10 Calories walking up a flight of stairs and 7 Calories walking down a flight of stairs. While not drastically large numbers and I am not going to stop other forms of exercise, those are Calories that I would not have burned anyway.
