The Silicon Valley Health Trend Making Doctors Nervous

Americans have spent billions of dollars tracking themselves: their steps, their blood oxygen saturation, their sleep cycles, their glucose levels. Is any of this data making us healthier? That’s the question the Opinion writer David Wallace-Wells poses to Dr. Rachael Bedard, an Opinion contributor and primary care doctor. In this episode, they explore what tracking ourselves, versus the population at large, can teach us and our doctors, and whether artificial intelligence might one day make sense of all of this data.
