i think that we live on as what we where...all of our actions, ideas, and impacts on others will create a never-ending wave...

if we curse at a man on the street, he may ho home and hit his son, which would make him depressed. and then he grows up, and his children always wonder why he is in an odd state...their wondering turns them into workers of the human perception, and they develope a new way of looking at things...which is viewed by the future humanity
