You wear a sensor on the back of your arm that continuously monitors your blood glucose level and dispatches alerts if a reading is too high or low.
You don “smart” socks that may help you avoid diabetic foot ulcers, or perhaps a smart ring on your finger that tells you your heart rate and how well you’re sleeping. And the increasingly intelligent watch on your wrist flags irregular heartbeats and summons help should you fall and become incapacitated.
