Being a good Hans Haacke student part of his influence on me is that there's no difference between a gallery show and a film - or even an ad and a T-shirt-in terms of cultural legitimacy. They're just different contexts in which to have some sort of communication.
The negative effects of combat were nightmares and I'd get jumpy around certain noises and stuff but you'd have that after a car accident or a bad divorce. Life's filled with trauma. You don't need to go to war to find it it's going to find you. We all deal with it and the effects go away after awhile. At least they did for me.
