At least in the United States, the incentives aren't there for a primary care doctor to spend time on their patients' prevention and wellness. They do some of that, but most physicians are reimbursed for putting in a heart stent or doing a big surgery. So the incentives need to shift a little bit towards prevention, and prevention that's personalized to the individual. One diet isn't going to work for everybody. Maybe we'll be using the DNA and other aspects to better predict how someone can be on a health track or improve their health. So I should be able to give you a prescription for this kind of exercise and this kind of diet. And then leveraging technology like mobile phones and other aspects, I should be able to track whether you did that or not. So if you're my patient, and you know that I'm your doctor and I'm going to get a report at the end of the month about how many steps you took or what your diet was or how many times you went to McDonald's, you might be a little more mindful and that might change your behaviour and that ten percent difference is going to make a big difference downstream. So part of it is smart behavioural change, which also can be individualized, based on personality type, I think, and part of it is leveraging technology to get insight into what your habits and lifestyle might be, whether it's for getting healthier prevention or treating a disease. If I know, if I say you’re taking four medicines and I can get a report at the end of the month of what you took and when you took it or why you didn't take it or what side effects you had or how that affected your physiology, and I can tweak things better based on that data stream, that would be a big benefit.
