in a lab they tested it with mice and rats -- "moderated" them .. all the ones who were more patient and "peaceful" died and became victims of others, got less food, were mobbed, had a shorter lifespan .. nature made us to survive == survival of the fittest -- suppressing this for a while will always create a backflash ! And no - humans are not different -- we are just walking and talking big Apes .. nothing else -- evolution works in all of our cells and genes ..
