The age is a little bit of an odd pick for America. Most young adults graduate from high school at 18. They graduate from college at 22. So, 20 is either when they have been working over a year already or when they are picking a major in college. I think ages 17–25 are some of the most stressful times in life. Trying to figure out what you want to do in life, trying to get a career started. It’s very very hard and often feels like you don’t know what you are doing. I don’t think it has changed much in the last 75 years. Prior to that maybe it was different. When there were more farms, more family businesses, more apprenticeships.
