And then in nurses, I think you're going to see something like the gig economy where the nurses are coming to your house. It's more like an Uber situation. If you need a nurse there's one there in 15 minutes and you can watch them approach on your phone. I think you're going to see a lot of medicine go to YouTube so that when people need to do simple things, such as here's an example, let's say you got an inhaler for your asthma and you needed to know the right way to use it and how to wash it out and all that stuff, all you have to do is have a good YouTube clip that's 30 seconds long and the person can learn what a nurse would have told them. So there's a whole lot of what a nurse does that's information and that can be moved to video and moved to the internet. And there's a lot of stuff that nurses do that's a small device test like testing your blood pressure, testing your temperature, and those devices are becoming commercial and accessible. You just do that yourself. And then maybe Amazon will be delivering small equipment and supplies someday. And it could be that the hardest thing you ever have to do is maybe dress a wound. And if you need somebody to do that for you maybe there's an app for that and you find a neighbor who will do it for $25. So that's sort of the broad scope. The idea is that if you can break down these categories in some kind of rational groupings then you can start to see which startups and which trends are working against those groupings. And then you can figure out how do you accelerate that. What is the best thing the government could do? What could you do as an individual? What investors could do? What's the best thing you could do to goose any of these effects that are already positive? What could be more positive?
