Patton was living in the Dark Ages. Soldiers were peasants to him. I didn't like that attitude.
The overall physical demand that Iraq has is pretty amazing. It's 130 degrees and the soldiers are carrying about 100 pounds of extra gear. It's a pretty rigorous schedule and routine for them.
You need some insecurity if you're an actor. It keeps the pot boiling. I haven't yet started to think about retiring. I was shocked when I heard about Paul Newman retiring at age 82. Most actors just fade away like old soldiers.
