 And is there any kind of risk that people will worry about what they see? I'm thinking about sometimes with the smart watches, there's been some research showing that people get worried about their sleep because they find that they're, you know, they thought they were sleeping well and then they find they're not. Oh, absolutely, yes. There's a risk that people, when we're learning as a society to know what this data should mean, there's a risk that people will misinterpret what it should mean. Like, for example, if you're good at your job, should your mental workload be high because you're working hard or should it be low because you're good at it?
