I had a different doc doing the procedure a couple days ago. Previous doc went into geriatrics or something. So, I'm half-sitting on the gurney in the 'event room,' all wired and ready to go, and the doc is verifying medical history, etc. Looks at me and asks, "are you a runner, or do you swim or cycle?"
"Yes, I cycle. Why do you ask?"
"Because your heart rate is 52. Good job!"
Wife, sitting there, says, "Busted!"
