Why we should all be wearing tech that can measure our health

On any given day, you'll find Dr Michael Snyder wearing about 8 pieces of technology to monitor his heart rate, skin temperature, blood oxygen levels, sleep patterns, and glucose levels. His smart watches and rings know if he's sick before he does. And that's the point says Dr Snyder, Director of the Center for Genomics and Personalized Medicine at Stanford University. He's known as medicine's most measured man with massive amounts of data from wearable technology and scans. His lab works on ways to track our bodies when we're feeling good, so we can spot trouble before it starts. He sees this as the future of medicine where we only go to the doctor when we're sick to care to keep us healthy.
