That's a very good question, a very important question. That's exactly why I was showing you the slide. We now are developing tools that can be applied, but right now these are not standardized diagnostic tools.
For instance, when you have cancer, you can go for cancer diagnostics. It is a standardized tool. When you get your blood pressure taken, it's a standardized tool. Brain imaging is only coming into its own now. That's why I think we need to put time and effort into making these sorts of tools standardized, so they can become diagnostic tools available much more widely.
