the other thing that is really big here is that when you're a patient getting this, you start to learn your own condition. >> i always take this with me and keep it fully charged. >> i want his quality of life to be good. he's an active guy, likes to do a lot of different things, including go hang out with his buddies and have a drink occasionally. that's okay. we want him to do that. in my view, moving the needle on health care, meaning getting good health care outcomes doesn't mean a 1940s model of health care where there's a single doctor that does everything and a low tech environment. it means the ruthless efficiency of digital applied over a very large population and saving the most talented, high-end people, which are the highly trained physicians to really take care of those people who need them. it means that instead of going for your annual check-up or to a doctor when you're sick, you get a phone call that says you're about to get sick. >> is the harder group to convince the physicians or the patients? >> there's no question, the physicians are the hardest group
