Interesting question, OP. I have been wondering the same thing. I sat down and thought about all of the doctors my PCP has sent me to over the last couple of years -- not because there was anything wrong with me, but because I'd hit some milestone age for a particular test. Of all of the tests I've taken, every last one of them has come back negative. I'm on no medication whatsoever, nor have I been sick or needing a temporary medication for any reason.

Two years ago, he sent me to see a dermatologist because my skin is quite pale and I guess he was concerned about skin cancer because of this fact. I've been there twice now and both times the dermatologist has marveled over how good my skin is...then I got a letter last week reminding me to make my appointment for next year. Why? What's the point?

I hate to think how much all of this has cost. No wonder insurance is so expensive. Now, I suppose the argument is that I could have something and not be aware of it, but then you have to ask, where do you draw the line?
