It's also interesting how your body weight affects you when you run a fever. My normal body temp is lower than the "normal" 98.6, I hover around 97.2 or so. So for me, anything above 99 is a fever and I am burning up. I had bronchitis last year and my fever was 102, which for me, was insanely hot. My obese boss is currently sick and had a fever of 102 and was acting like he was knocking on death's door, when the reality is that his normal temperature is around 99 degrees. There's a world of difference between those two, even though our fever temperatures were the same.
