By looking at his data, he's learned exactly what he needs to be his most productive self, such as setting the lights to a specific shade or programming the air levels in his bedroom so he can sleep soundly. He's even monitored his heart rate while watching porn to become more aware of his sexual preferences: "I thought I was into certain types of people, but learned what I actually like most." He's also lost more than 100 pounds along the way, just by tracking his daily habits and making small changes to be healthier.

Even his dogs are tracked; a product called Tagg logs their daily activities.

He's been called everything from a cyborg to an alien for his extreme data collection routines, but Dancy is the future tech experts say is coming.

Dancy is the ultimate example of two revolutions underway in tech: the Internet of Things (smart thermostats, garage doors, toothbrushes, tennis racquets) and quantified self (what you learn about yourself from trackers). Apple and Google are the two biggest companies expanding their efforts in the "smart home" market, which is projected to bring $1.9 trillion to the global economy by 2020, according to Gartner Research.

Dancy, who quit his job in March 2014 as an IT specialist, has flown all over the world to give keynote presentations at major conferences and companies, including Google, and spent nearly $40,000 testing connected gadgets in the past year.

Soon, he'll transition into a role as chief digital officer at Franklin, Tennessee-based Healthways, where he'll work with existing products and developing next-generation wearables in healthcare. He'll pack up his sensors and personal tracking devices to install in a home he's purchased down south.

"Everyone wants to know if they will be like me in the future, but everyone is already like me; they just don't think about it like that," he says. "Your phone is already collecting information about you and your life. If you use a credit card or a car GPS system, you're already being tracked. But that's Big Brother. When you take control of it yourself, that's Big Mother, and that relationship is nurturing, kind and not controlling.

"I'm the most connected man in the world to myself," he says. "I'm not the most connected man in the world to technology. Technology was the route."
