In late June, Robert F. Kennedy Jr. told Congress that he wants all Americans wearing health-tracking devices within the next four years. Wearables, the Health and Human Services secretary said, are “key” to his Make America Healthy Again agenda. “It’s a way people can take control of their own health. They can take responsibility,” he told lawmakers. “They can see, as you know, what food is doing to their glucose levels, their heart rates, and a number of other metrics as they eat it, and they can begin to make good judgments about their diet, about their physical activity, about the way that they live their lives.” The agency is now preparing to launch a public-health campaign encouraging people to use these devices.
