Congratulations, you've just created the world's worst database design! Using age as a primary key is like using a sandwich as a doorstop - technically possible but fundamentally wrong. Primary keys should be unique and unchanging, but unless you've discovered the fountain of youth, your age changes every year. Plus, there are roughly 8 million 17-year-olds on Earth right now, all trying to register for your app. No wonder it's complaining! Next time, maybe try something truly unique... like I don't know... an ID?
