The oldest known animation was discovered in a cave in Iran and is thought to be over 5,000 years old. The animation consists of a series of images of animals that are thought to tell a story. The art of chicken sexing is a lucrative one that is often passed down from generation to generation. Chicken sexers can earn up to $100,000 a year and often start working in the profession when they are just children.
