 I think one of the things that people are most surprised about when they come into Crossroads and they have that first new patient exam with us is when they leave the office and they're given their checkout packet. And it includes a map of where everything in the spine connects to as far as the nerves go. So, for example, that T3 and T4 and T5 area connecting into the lungs. Yeah. And to be thinking about, wow, my lung function or my lung dysfunction could actually be related to my spine.
