It seems that humanity shares just about everything we have down to our organs. Humanity knowingly and unknowingly shares ourselves and belongings throughout our entire existence. It’s very convenient for us to think that we choose what we share, but the truth is that the governing force/nature of the universe forces us to share. Some even have to share their spouses or romantic partners willingly and unwillingly, mostly unwillingly. Once we evolve in our understanding that we are sharers and that sharing is not the nice thing to do, but what we must do, then humanity will become a more peaceful and coherent society. Remember you share the air your breathing right now with every living creature on this planet!
