Die, Chotomies!

There are all sorts of dichotomies in ""Eat or die" is only an unpleasant threat." There is candy and there is destruction. There is love but also confusion. Prison and Safeway. Eating or dying. What's the difference or significance of apples vs. coconuts. Do you know? Lettuce vs. spinach. Disapproval vs. approbation. The flesh of hands but being oversized and machine-like. "I didn't like being in prison but I lifted weights a lot." What do the dichotomies mean? What does it mean that the last sentence is "I don't know what I mean"?
