Why Humans Outlive Most Animals
On the 1st day, God created dogs, saying “Sit all day by the door of your house and bark at anyone who comes near. For this, I will give you a 20 year life span.” the dogs said, “10 years is enough.” So God agreed.
Then God created monkeys, saying, “Entertain people, do tricks, and make them laugh. For this, I will give you a 30 year life span.” The monkeys said, “20 years is enough.” And God agreed.
Then God created cows, saying, “You must go into the field with the farmer all day long and suffer the sun, have caves and give milk to support the farmer’s family. For this, I will give a life span of 60 years.” But the cows said, 20 years is enough.” And God agreed.
Then God created human beings, saying, “Eat, sleep, play, marry and enjoy your life. For this I will give a 20 year life span.” But the humans complained, saying, “Only 20 years? Could you possibly give us our 20 years, the 40 years the cow gave, the 10 years the monkey gave back and the 10 years the dog gave back? That makes 80 years.” Once again, God agreed.
This goes a very long way in explaining why for the first 20 years we eat, sleep, play and enjoy ourselves. And why for the next 40 years we slave in the sun to support our family. It also explains why for the next 10 years we do monkey tricks to entertain the grandchildren, and for the last 10 years we sit on the front porch and bark at everyone.
