This isn't completely relevant, but I'll tell the story anyway. My boomer brother in law worked for 30 years building a construction/paving business. It was physically tough on his body. He decided to take a job as a trucker since he had a class A commercial drivers license and he didn't have the physical stamina anymore. Within a few months he was considered the top driver, getting his choice of truck and routes. I congratulated him, saying what a great job he did switching jobs at his age. He laughed and said he didn't deserve congratulations. He said " these kids in their twenties and thirties just don't show up for work, or they fail the drug test." The manager told him he never had such a reliable driver before.
