(Yes, I'm back, thanks for the nice comments. I will try to have a thicker skin next time.)

Since you brought up dentistry, what I don't understand is why folks are so reluctant to get regular eye exams, even every one year if not every two, and yet they jump to go every six months to get their teeth cleaned. And my parents told me their dentist in Florida recommends every 3 (or was it 4) months!
3 - 4 months!!! (And their teeth are just fine.) Does it have something to do with the fact that their insurance will pay for it? Any comments from the anti-insurance crowd?
