Bit of twinging in the knee again today and I don't know why. I haven't pushed it. I have to take the day off anyway b/c i am giving blood today. I like giving blood it makes me feel good. Reading that Chris McDougall book born to run again. Good writing. He took me down a couple of paths that left me no where but that's a bit like trail running. Walked to the train barefoot today. I am loving these cool mornings. Forgot to bring the paperwork for the clinical trials yet again. I dont thinkmy heart is in this.
