I probably haven't been to a doctor for years and years. Like most Americans I have pretty shitty health insurance, and it's mostly about avoiding unnecessary expenses. I don't have any burning desire to pay a doctor, a blood test lab, and all the other various administrative leeches, just for them to all tell me everything's good. If something happens and I get seriously ill, I accept that I'll be paying through the nose for it, but that's the case whether or not I waste time/money on "checkups".
