then half the people living today are younger than you are. World's median age is around 31. Imagine all those people who have seen less than you, learned less than you. By a slight margin they make up the bulk of humanity. Congrats on becoming an elder. Go teach them what you know.

And others know even less than you. This is the way of the world and the context in which we must continually mold it!
