Think about this:

Go to the hospital for chest pains that turn out to be that Tai food you had for lunch. (Happened to an marathon runner/pilot friend of mine) Now he needs to do annual stress test with full EKG to maintain his Class III.

How about your love for bacon? All of a sudden you are on new cholesterol meds that you didn't check to see were on the 1950's tech-level approved list. Oops.

How about winning the battle with cancer?

Now see how much that $120 Class III medical costs.

I could go on and on. This isn't just an old person's problem. There are a million pitfalls that can make a Class III horribly expensive to maintain. It's an outdated, unnecessary, government boondoggle that needs to go away.
