My knowledge of how well my body is functioning is extensive.
Call it a perk or a hazard of the job, but as the result of many, many scans over the years in the quest to find the best, I know my exact cholesterol levels (high), my blood pressure (low), and lot of other bits of information I can — and often do — dole out at the drop of a hat, should someone be unfortunate enough to enquire after the state of my health at a dinner party.
