For years I've had a patient who is a gym teacher. As you might expect, he's pretty fit. Well into his 60s, he can do an impressive number of pushups, as he demonstrated one morning in our exam room.

He surprised me in a different way at an appointment several months ago. He pulled out results from medical tests that he'd had done at his church. He and many of his fellow congregants had each paid about $150 for screening tests that they were told could see if they were at risk for strokes, clogged leg arteries and other problems.
