God created the donkey
And said to him.
"You will be a donkey. You will work un-tiringly from sunrise to sunset
carrying burdens on your back. You will eat grass,
You will have no intelligence and you will live 50 years."
The donkey answered:
"I will be a donkey, but to live 50 years is much. Give me only 20 years"
God granted his wish.
...........................................
God created the dog and said to him.
"You will guard the house of man. You will be his best friend. You will eat
the scraps that he gives you and you will live 30 years. You will be a dog.
The dog answered:
"Sir, to live 30 years is to much, give me only 15 years."
God granted his wish.
...........................................
God created the monkey and said to him.
"You will be a monkey. You will swing from branch to branch doing tricks.
You will be amusing and you will live 20 years."
The monkey answered:
"To live 20 years is too mush, give me only 10 years."
God granted his wish.
...........................................
Finally God created man and said to him.
"You will be man, the only rational creature on the face of the earth. You
will use your intelligence to become master over all the animals. You will
dominate the world and you will live 20 years."
Man responded:
"Sir, I will be a man but to live 20 years is very little, give me the 30
years that the donkey refused, the 15 years that the dog did not want and
the 10 years the monkey refused."
God granted man's wish. That is life
