Human memory is shit, easily altered, and the worst way to recall an event. The courts are finding this out. When video contradicts someone's story, I'm inclined to believe that the person honestly thinks the event happened as they remember it. But memories can be fudged. People can remember things as an event when they never happened. Our brains are amazing things and the more I know and learn about how the mind works the more in awe I am that we Humans have been able to do ANYTHING other than hunt antelope on the plains of Africa. You do not remember an event... the way your brain works is that you recall the last time you remembered something. each time you pull that memory a game of Chinese fire drill is going on in your grey matter.
The brain and the mind fascinate me.
