“Grahn takes my hand and slips it into a clear, coffeepot-looking contraption he calls the Glove. Inside is a hemisphere of metal, cool to the touch. He tightens a seal around my wrist; a vacuum begins pulling blood to the surface of my hand, and the cold metal chills my blood before it travels through my veins back to my core. After five minutes, I feel rejuvenated. Never mind the hangover. Never mind Bon Jovi. I keep going for another half hour.”
