 Yeah, there's been various devices for the last five to ten years that are coming out, but it was really early devices. If you remember the oldest smartwatches and physical activity trackers we had, they were nice first new devices, but it took a long time to get to the finesse of final devices by now. So we expect the same thing to happen with neurotech over the next 10, 20 years, that it becomes embedded in more things, maybe in people's glasses, they would have some sensors in there since they're wearing them anyway.
