The day I had to jump start my car, I suffered. I was bundled up well, but did not have adequate gloves. The jump start went fine, but afterwards, my hands were so cold that they hurt and I could barely move them. I left the car warming up while I stayed inside my apartment in pain from the cold in my hands. I mean, I was yelling in pain so bad that the neighbor lady checked on me to make sure I was all right. After about 20 to 30 minutes, I felt fine. It was pretty scary. I think if I hadn't stopped to warm up my hands, I could have gotten hypothermia in them.
