For me, it's probably that there isn't much that seperates us from the animal kingdom after you've stripped away all the self-imposed laws and societal conventions (depending on which 'society' you come from). I'm not looking to be proven wrong or attempt to prove others wrong. I'm simply interested to hear what you believe has been the most valuable lesson you've learned thus far, if there's been one. It can stem from anything and/or be relevant to anything. So, what's it been?
