Ace that is a good illustration, I was going to say that everything we are and all of our emotions and personalities are developed in the brain. All emotions we express towards ourselves or our fellowman first must start as a thought an idea. We then choose to act upon those thoughts and ideas which through our passion are later translated into emotions. Our life experiences also shape how we relate to others in our community and strangers as well, as you stated Ace all emotions are chemically based.
There is nothing people will not maintain when they are slaves to superstition
