Why is it said that people born in the year of 45 are donkeys? Which historical story does this come from?

It is said that when God created creation, he gave humans a life span of thirty years. He wanted humans to live happily, but humans thought it was too few. God created the donkey and asked it to work hard all its life and live thirty years. However, the donkey thought it was too painful and asked for his lifespan to be halved. The man immediately requested that the lifespan that the donkey did not want be added, so that the man could live forty-five years. Later, God created a dog and gave it a lifespan of thirty years, asking it to guard property and stay awake at night. The dog also felt pain and asked for its lifespan to be halved, and the man asked to add the lifespan that the dog had lost, so he was sixty years old. Later, God created the ape and gave it a lifespan of thirty years, saying that it could live a life without any worries, but it could only have a bald head and a wrinkled face. The ape still did not accept it, and also lost half of its lifespan. Gave it to people. Therefore, people are destined to work hard like donkeys for fifteen years, be doubtful and restless like dogs for fifteen years, have dull eyes and do nothing like apes for fifteen years, and live like a human for only thirty years.
