all you need are yearly check ups

Good luck with that. I've found that doctors are too busy to give "just a checkup" for adults. If you show up to the doctor's office and say "I'd like a checkup," they will respond with "What's wrong?" You CLEARLY aren't in a doctor's office if nothing is wrong, because then you'd just be wasting the doctor's time!

I don't think I've been in a doctor's office for six or seven years.
