The ability to diagnose an imminent heart attack has long been considered the holy grail of cardiovascular medicine.

The stethoscope for listening to the heart is over. It's obsolete.

Of course, the medical profession doesn't like D.I.Y. anything.

A lot of the diagnosis and monitoring functions will be done through little devices - smartphones - by the patient with computer assistance. So it's a real big change in the model of how we render healthcare.

For diabetes in particular, we know there's a relationship between lack of glucose regulation and complications like blindness and kidney failure. So if you were diabetic and you knew that you could get your glucose in a tight, normal range just by adjusting your lifestyle, wouldn't that be great?

Medicine is still all about treating populations, not people - one-size-fits all treatments and diagnoses.

Medicine is incredibly ritualistic.
