What an interesting read, now if I could give my 2 cents worth. I believe that the factor of motivation changes the path our brains chose. For example, if I were the person reaching for the fruit on the lower branch and the fruit was for me, then yes I would just grab the first easiest one I see, HOWEVER, if the fruit was for a loved one and the fruit higher up in the tree were more plump and looked more appealing, then I would go the extra mile to get the loved one the better fruit. So my path was motivated by love. Just a thought. Thanks for sharing
