According to an old belief, during the time that God was creating the world, it was thought that people would only live 20 to 30 years and then a dinosaur would come along and devour them so they would be able to live their whole lives without feeling any pain. Even though pain is one of the most common and important health problems, and is usually a messenger of a more serious underlying health problem, it has not been taken seriously for ages.
