This speaks somewhat to a theory I have always had about actual "memories" being passed down via genetics through generations. This is where instincts come from in the natural world really. I'm not talking about "past lives" but actual memories/experiences from ancestors being imprinted in our DNA.
I realize this may seem a bit out there to some of you but I really think about this from time to time. It may actually explain where our obsessive fascination comes with certain historical events. Something to think about and discuss.
