a very specific example that we've all experienced now, that was the COVID. That I shouldn't say was because the 500 people a day are still dying from from disease. But that's a great example of an adaptive challenge, because, you know, there was so much that we didn't know, we didn't know how we didn't know as much as we want needed to know about its transmission. With there was a lot that we didn't know about the impact. The tools that we had for treatment were rudimentary. Okay, for the person on their stomach, you know, I mean, there were things that could be done, but we didn't have vaccine. And we certainly didn't have the, the antivirals that we have now, whatever. And, and the impact that that had on on the workplace was enormous. From my own experience with teaching, it was those, when we realized we had to send all of our students home, then the question was, well, how the hell do we continue providing an educational experience for undergrads, graduate students, Executive Master students, and of course, the people who had been working in online education, then became like, revered experts, which they were not before all that happened, unfortunately. And then everybody was thrown into a situation where, okay, we have to learn, life goes on, organizations have to produce things, they have to work, they have to provide services, how are we going to do that in this context? And, boy, I mean, you've talked about a complex situation where now the old rules did not, did not apply anymore. So there had to be a lot of collaboration, a lot of creativity in some, some has led to some, some really great outcomes and, and other ways, you know, there's certainly some challenges. I mean, our kids are kids, I think, really suffered. And we're seeing that, you know, in children that were not in school or not consistently in school for two years. And behaviorally, they're, they're way behind where they, they ought to be with their social emotional development. Hopefully, they'll catch up. But that's a great example of as a whole world, we had to face a pretty complex situation for sure. Yeah.
