While I don't think that I've worried about post-modern theory, ever, I know when I was the most materially impoverished and dealing with a lot of emotional and physical abuse, my worries encompassed much more than just how I was going to afford to eat. That general feeling of dis-ease was an almost constant in my life. I could never decide whether it was a physical or mental kind of unhealthiness, but it was always there, nagging.
