Crazy!

For those of you who are not familiar with the Phineas Gage story it is crazy. Gage was a railroad construction foreman now remembered for his incredible survival of an accident which drove a large iron rod through his head, destroying one or both of his frontal lobes altering his personality. I had hear this story a couple of times and the rendering I saw of the spike was not that large. Below is the spike next to his skull (kept at Harvard).
