So man lives seventy years. The first thirty are his human years, which are soon gone; then is he healthy, merry, works with pleasure, and is glad of his life. Then follow the donkey’s eighteen years, when one burden after another is laid on him, he has to carry the corn which feeds others, and blows and kicks are the reward of his faithful services. Then come the dog's twelve years, when he lies in the corner, and growls and has no longer any teeth to bite with, and when this time is over the monkey's ten years form the end. Then man is weak-headed and foolish, does silly things, and becomes the jest of the children.
