Well now there's essentially a virtual colonoscopy.

I won't ask who here's had a colonoscopy, but if you're over age 50, it's time for your screening colonoscopy.

Let's get personal. I won't ask who here's had a colonoscopy, but if you're over age 50, it's time for your screening colonoscopy.

Clearly, Patient B suffered more his colonoscopy was longer, and every minute of pain that Patient A had,

Therefore, there is no need for those people to have another colonoscopy sooner than five years after the first screening.

Now, what you could do with Patient A, and we actually ran clinical experiments, and it has been done, and it does work you could actually extend the colonoscopy of Patient A by just keeping the tube in without jiggling it too much.
