Medical settings occupy just 1% of our time and space. Although the data generated there is valuable, it remains siloed, intermittent, and unstructured. As long as healthcare is confined to this narrow 1% window, its diagnostic power will stay fundamentally limited. Life settings make up the remaining 99%. In this much larger observational window, the earliest signs of disease appear—yet are too often missed, even dismissed. Life settings offer an opportunity to generate health data and insights at scales orders of magnitude greater than today’s medical setting paradigm.
