Since this thread is chock full of anecdotes, here's mine that is the exact opposite. I was completely healthy into my late 20's. I started a new job at 30. I got health insurance and figured for my 30th I'd get a checkup ... my first exam since I was 18 under my parent's plan. My blood pressure was high, so they did some tests which uncovered portal hypertension, and found I may eventually need a liver transplant. Zero history of it in the family. Good thing I had a checkup because I thought I was the model of health. Again, since these are all anecdotes, I'm sharing. Yes be alert and ask questions but don't just blow it off. Maybe not yearly, but at least twice a decade maybe?
