I've certainly experienced physical pain in my life.

The greatest evil is physical pain.

The only antidote to mental suffering is physical pain.

Marathons are hard because of the physical pain, the pounding on the muscles, joints, tendons.

But I started it when I was going through a transitional time in my life. At the end of it, it really sort of symbolized it. I had made room to change, and room to grow. I recorded it in a little room.

I open the book and turn to the next page. Day three.

I started screaming today.

And those four words hit me harder than the worst kind of physical pain.
