Why our minds are mush

I was in the supermarket today buying bread and I counted, in the bread aisle alone, 81 different kinds of bread. You know bread? Flour, water, yeast, knead, bake. That stuff. 81 choices. This doesn't include the fresh bakery counter, english muffins, wraps, rolls, and other bread related items. There were 17 different whole wheat bread packages.

My hypothesis is that this is way too stressful for people. Back in the day it was fight or flight, or maybe grow something instead of hunting. Now, unless you're an experienced shopper, you can't even figure out what to buy. You know the fortified skim milk? The kind that's "fat free, but tastes like 2%"? There are now more kinds of that than there are regular skim milk. We may think we want this kind of choice, but we certainly don't need (or even knead) it, which makes me think that it's unsustainable.
