Guest: Michael Snyder, PhD, professor of Genetics, Stanford Your Fitbit can tell you how many steps you took in a day, but what if it could pick up subtle cues that you might be sick, even before you realize you’re not feeling well? The technology to do that is pretty much already here. What we need is computer programs that can collect that steady stream of data about our body temperature, heart rate, oxygen levels and such and make sense of it.
