I'm working in Nashville, Tennessee So what I'd like to do is have you both just tell us about You know when and why filter retrieval became an important element of your practice. Tell us about your filter retrieval service And its current state and how it's evolved Maybe go ahead and start with you Bob Oh sure Gosh my interest and I see filters goes back probably when you guys were in high schoolI got more interested in filters probably in the mid-late 2000s about the last 10 years
