People go through their whole life only to discover that they've had a reaction to certain foods that they never had issues with before. That's enough to change your religion right there. Yearly check ups are or should be customary once we hit our 50's and my personal favorite is having my 30 year old female Urologist check my prostrate. If my HMO allowed 2 checkups I'd be the first in line every time and yes, she's that cute!
