There was a study a few years ago regarding decisions. Turns out the brain made the decision before the conscious mind was aware of it. The mind appeared to rationalize a completely automatic "decision" after the fact.

The sthtu affects the wiring of your brain, and therefore how it processes. Different experiences result in different connections being made within the brain, and that happens pretty much all of our lives. Not really vague at all.
