I am a machine - I do not feel pain

Today's mantra as I was running 6 - 400's with sarah was "I am a machine, I do not feel pain." This just came to me as I was running. I suppose a muse just whispered this into my ear. It was so inspiring. I decided to ignore the knee pain and new popping sound I was hearing and just sauntered on. At work during lunch, I decided to do research and self diagnose myself. I think I have runner's knee. Tonight I will ice my knee and hope for the best. Tomorrow is a day off, Friday is an easy run and Sunday is Bay to breakers. If my knee still hurts then, I will just join everyone else and drink a beer!
