I weigh in at about 120 pounds. I'm sitting in a strangers house with a friend who brought me along to "do some business" so I could get a ride to work. A guy easily twice my size looks me up & down says to me something along the lines of "If this goes wrong you're first". I was terrified; I knew I couldn't handle him, but I kept my cool & told him to try me. I figured I'd take a beating but I knew where the exits were. He stayed calm and so did I. Fear is good. It puts your guard up. If you can control it your fear will help you make good decisions. If you don't control it your fear will lead to panic; panic will lead you to make bad decisions. I don't fear a virus because I've dealt with them before. If I get a fever I tend to it. If I'm sick I deal with it. Like every reasonable person should.
