Adrenaline

While I have no real interest in science or anatomy, I find the body and it's reactions to situations to be fascinating. Today's example is adrenaline. I had a work-related incident last night which woke me up @2:15AM. It kept me occupied until 5AM, and when I got back to my room, I couldn't fall asleep until 6. As soon as I got called, the adrenaline kicked in, and I was alert and ready to go; nothing could stop me. And while I feel wiped today, I also realized that the adrenaline will kick in on marathon day and keep me going. For, if I could be active and alert after a long day (including my long run) for almost 4 hours, I think the adrenaline will give a 4 hour marathon time. So, here's hoping!
