The Professor of Philosophy just going on a research the other side of the river boards a canoe and as he was about to enter the canoe , he picked pebble of stones by the river shore are asked the boat sailor: Boy do you know anything about geology? The boy answered 'NO'; then you have lost 10% of your life... The boy kept quiet. Just as they zoomed off the Prof removed the leaves of a plant he plucked while on the way...again he asked the boy: Boy, do you know anything about biology? Again the boy said no...the Prof told him that he has lost 40% of his life...the Prof went on picking water and asking about hydrology and in turn telling the boy he has lost 60% of his life...by now the boy was angry but what could he do?

Now suddenly as the boat was still sailing on the river, the whether changed and the sea became troubled and boisterous... Unable to steady his boat and their life hanging in danger... The Boy decided to jump out of the boat and save his life...but then he asked the Prof... OGA, do you know anything about swiminology.. The Prof said NOoooo.. The bouy told him.... Now you have lost 100% of your life. Though the boy could save the Prof... But he didn't cos Prof has reduced him to a nobody. So The Prof lost 100% of his life.

Lesson: nobody knows everything .... But everybody knows something. Let us respect one another.
