Totally agree, although perhaps the real gift of this technology will be from the fact that people can be more aware of the underlying conditions (high BP) and tighter feedback loops on how to reduce it / manage it vs. just helping notify about an acute emergency situation. As I typed the above sentence out, I thought "why not both?". Use the technology to reduce your risk, but in the event that the bad event still happens the notification could save your life.
