That's one of the toys I would like to buy! Endoscope for engines and stuff. In the medical field it is wild to see the problem first hand. Without cutting or making an opening on the patient.
I had an appointment with a surgeon about circulation in my right arm. He walks into the room and says:
Hey ! I did your Colonoscopy!
You probably don't remember me. I was at your other end. Hee Hee,
YEAH DOC< WHAT A GREETING!
Like you so smart to remember. You just searched my name on your data base!
