There likely is lots of money in health. Almost everybody claims it’s the most important thing to them, the aging population gets more health problems and many of them also get more disposable income (kids left the house, fewer holiday trips due to declining health)

That’s probably a big reason for the existence of the Apple Watch and HealthKit.
