 To the doctor. I've never heard this. To let him know how he's progressing, what steps he's doing every day, and all of that. Oh, so he can't cheat. Yeah, he can't cheat. Wow, that is brilliant, brilliant technology. I never heard that until today. Didn't even know it was available. It's fairly new, but it's not brand new. They've been doing it for a few years. Went to South Bend Ortho in South Bend. Good for them. They're really high on this. Happy with good.
