I WEIGH JUST a little under two hundred pounds, have brown hair, blue eyes, and a full set of teeth. As far as I know, my thyroid gland pumps the right hormones into the twelve pints of blood that circulate in my arteries and veins. At six feet two inches, I have long femurs and tibias with solid connective tissue. Both of my kidneys function properly, and my heart runs at a steady clip of eighty-seven beats per minute. All in, I figure I’m worth about $250,000.
