@Setanta,
All this shows is that it really takes less of ones brain to understand and accept the obvious than it does to make up a complex story line of gods and demons and to create a complex system of authority to maintain this story.
I wonder if that part of the frontal cortex is also the location from where entertaining stories and jokes originate?
Hell, I coulda told you that without spending a huge pile of cash on studies to reveal the obvious.
