I'm curious about the role of social when it comes to these road activities. Let's talk about this idea of cognitive resource allocation. Because you say that your cognitive resources can drain and that affects your performance in the short term. We find that for most people there are peak focus times are mid to late morning. And then again, mid to late afternoon like two to three p.m. Most people actually don't start their day doing their hardest tasks but they kind of ramp themselves up.
