The human head is the same approximate size and weight as a roaster chicken.

That is from a book I just finished called "Stiff" by Mary Roach. It is about the science of human cadavers... oddly, it's funny. It was recommended to me by my anthropology professor. It was strange, but a very good book. I recommend it, if you can find it. Now on to my next, less entertaining read, "Practical Guilt". More or less a text on the moral dilemmas of emotion and society. It's by P.S. Greenspan, I'll find out who he is in a few days...
