Chris Dancy of Denver is wired to 700 sensors and uses a range of devices, apps and services to record all kinds of details about what his body is doing, reports The Daily Mail. He takes the idea of "quantified self" to the extreme, and it's earned him the unofficial spot as "most quantified person in the world." Dancy has spent the last five years "bringing on two or three new systems a week," which he uses to monitor and record nearly every aspect of his life and health (even his dogs have a monitoring system).
