God created the mule, and told him, "You will be a mule, working constantly from dusk to dawn, carrying heavy loads on your back. You will eat grass and lack intelligence. You will live for 50 years."
Then God created the dog, and told him, "You will hold vigilance over the dwellings of Man, to whom you will be his greatest companion. You will eat his table scraps and live for 25 years." And the dog responded, "Lord, to live 25 years as a dog like that is too much.Please, no more than 10 years." And it was so. Finally, God created Man-and told him, "You are Man, the only rational being that walks the earth. You will use your intelligence to have mastery over the creatures of the world. You will dominate the earth and live for 20 years." And the man responded, "Lord,to be Man for only 20 years is too little. Please, Lord, give me the 20 years the mule refused, the the 15 years the dog refused, and the 10 years the monkey rejected." And it was so. And it is so.
