 Once we turn 40, we actually were able to tap into this thing we've been talking about, which is feelings. And more than any other device or anything, we actually have been able to ask ourselves now, what is my desire to train? And then we work our don't based on how we feel. You know, why? Cause it matters. It matters. We're both very motivated trainers. We love to work out and we always want to move. So we really have tried to listen to that voice that's saying, I don't actually feel that well. And on those days, we just walk. We work with this professional cyclist who's local named Kate Courtney. She's a mountain biker, world champion. And the morning that she won one of our world championships. And a complete athlete. Complete athlete. Like one of the most complete athletes of ever. She is total complete, amazing athlete. But she woke up on the morning of her world championship and she had like a 12 in terms of her recovery score on her ROOP, like deep red, the worst red you can get. And she actually had the wherewithal to be like, that's not how I feel. I feel great. She went out, destroyed everybody, won a world championship that day. And then she called WOOP and said, hey, your algorithm's wrong. And WOOP was like, no, it's not. And then they went back and like, did their secret world stuff. And they're like, you're right, the algorithm was wrong.
