 Yeah. I think it's been quite a big learning process. Our challenge was about trying to identify the flows of plastics in postal sector data. And I guess one thing I learned is it's really hard. You know, there's a lot of sustainability challenges attached to the postal sector in e-commerce, but they're quite hard to see and they're quite hard to see in the data as it currently is. But I think what I kind of learned is that while that's true, I think the postal sector is quite well positioned to have a better understanding. It's got a big view over a lot of different topics. And so a really interesting kind of viewpoint. I think I also learned a bit about how to try and bring together quite complex teams around these challenges, you know, starting from a quite difficult sustainability challenge and really bringing in some great minds, data analysts, people from the postal sector to try and tackle them. So yeah, hopefully I can learn something from that.
