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."The mule answered, "To live like this for 50 years is too much. Please, give me no more than 20." And it was so.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.God then created themonkey, and told him, "You are monkey. You shall swing from tree to tree,acting like an idiot. You will be funny, and you shall live for 20 years."

And the monkey responded, "Lord, to live 20 years as the clown of the world istoo much. Please, Lord, give me no than 10 years." And it was so. Finally, God created Manand told him, "You are Man, the only rational being that walks the earth. Youwill use your intelligence to have mastery over the creatures of the world. You willdominate 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 themule refused, the the 15 years the dog refused, and the 10 years the monkeyrejected." And it was so. And so God made Man to live 20 years as a man, then marry and live 20 years like a mule working and carrying heavy loads on his back.

Then, he is to have children and live 15 years as a dog, guarding hishouse and eating the leftovers after they empty the pantry.

Then, in his old age, to live10 years as a monkey, acting like an idiot to amuse his grandchildren.And it is so.
