It's really about putting health into the aging years. I think we know an awful lot at this point about the risk factors that make you unhealthy and live a shorter and poorer-quality life. What we haven't really been able to master as well is how you deliver, in an effective way, interventions that turn that around.
That's where I think technology, as we've already discussed, actually has a power that has never been there before to use the right people, health professionals, in a way they've never been used before—at the right time, at the right place, for the right person—and empower people who don't need that intensive help through other means.
I think it's a really exciting time. Now it's a matter of how you harness it in such a way that you don't get a lot of junk out there in the app world and you get things that really matter. How do we marshal the science to make sure we get that kind of evaluation done so that we know how it's going to work?
There was a recent example with dermatology, where they took pictures of skin lesions with two different products, one being actually highly successful. It was reviewed by a pool of consultants. Others were generating an awful lot of false negatives, meaning that they truly had treatable—should have been in there, could have prevented that—skin lesions.
I think this is the kind of thing that we really are quite aware of in the scientific world. We really need to make sure that we cover the full spectrum, from co-innovation of new things to evaluating what's out there, so that we can provide the best guidance.
