So I think it's another...so there's the lactate part of it where you're increasing the lactate, and it's a quick sort of...and it is. Like I've measured my lactate spikes up, you know. I don't get up to the levels that my husband did. I'm more like a 7, 8 millimolar, and he gets up to like 14. But after 20 minutes, I'm back down to 1 millimolar, to my baseline, basically. So is there something with that lactate going intensely up, but also the shear force, I think. There's another interesting component to that that I think needs to be calculated into this equation because I'm seeing increasing data on that, not just with respect to brain health, but also people that have cancer.
