 By the way, pushing the envelope. Yeah. We often think of it means a paper envelope. It does not. No. It is a reference to a mathematical envelope. And, of course, it's used in aviation, used in rocketry, and has something to do with, you know, where the outer limits of consecutive curves. I'm not going to get into the mathematical whys and wherefores. I wouldn't understand that. It's way beyond our, you know, comprehension. But that's where it comes from. Not the paper envelope, but the mathematical envelope.
