The meaning of life !

From the beginning of time mankind has been obsessed with one question - " What is the meaning of life ? "
From the darkest cave on the highest mountain the wise ones have pondered this over many centuries - and provide this answer.

One day God created the dog and said: " Sit all day by the door of your house and bark at anyone who comes in or walks past. For this I will give you a life span of twenty years ".
The dog said: " That's a long time to be barking. How about only ten years and I'll give you back the other ten ? " So, God agreed.
On the next day, God created the monkey and said : " Entertain people, do tricks and make them laugh. For this I will give you a twenty year life span ".
The monkey said : " Monkey tricks for twenty years ? That's a pretty long time to perform. How about I give you back ten years like the dog did ? " And God agreed.
On the next day, God created the cow and said : " You must go into the field with the farmer all day long and suffer under the sun, have calves and give milk to support the farmer's family. For this I will give you a life span of sixty years ".
The cow said : " That's kind of a tough life. You want me to live for sixty years. How about twenty - and I'll give you back the other forty ? ". And again God agreed.
Then on the next day God created man and said : " Eat, sleep, play, marry and enjoy your life. For this I will give you a life span of twenty years ".
But man said : " Only twenty years ? Could you possibly give me my twenty, the forty the cow gave back, the ten the monkey gave back and the ten the dog gave back - that makes eighty - OK ? " " OK " said God. " You asked for it ! "
So, that's why the first twenty years we eat, sleep, play and enjoy ourselves. For the next forty years we slave in the sun to support our family. For the next ten years we do monkey tricks to entertain the grandchildren - and for the last ten years we sit on the porch and bark orders at whoever is cleaning our house and cooking our meals.

Life has now been explained to you.
