Goat 1: I am terribly bored, tell me something interesting
Goat 2: Want to hear about one of the greatest conspiracies that goes on in this world ?
Goat 1: Never heard of it, what is that ??
Goat 2: Well, you might have been told countless times that old people are wise and you have to respect your elders, listen to their opinions, blah blah..
Goat 1: Yes, so whats with that ??
Goat 2: Here is how it started, almost all men want a sense of authority over others. The problem with holding a 'title' or 'respectable job' or any other thing that gives you authority is you are always in direct competition with someone and one day or other you will loose that authority.
Goat 1: so what ?
Goat 2: the wise guys needed something, that will always be there at their defense. There it was, time. Yes, all people grow older everyday and that was the best defense. Spread the word the older you grow wiser you are.
Goat 1: mmhm
Goat 2: The idea was so contagious, irrespective of civilization, religion, etc it spread like wild fire. No matter what you have done when you were young, once you grow older, you have to be treated with utmost respect, elders thoughts, ideas and opinions matter the most.
Goat 1: How do you know that ??
Goat 2: Because I am older than you and I am wiser than you.
