I have a relative (uncle) who recently went in for a colonoscopy. They were "lightly sedated", whatever that means; however, they are now having some short-term memory issues post-procedure. This is interesting given the family history: a parent (uncle's sibling), post-general anesthesia, went from mild memory issues to diagnosed dementia (memory care for nearly a decade now).
And now a sibling has their GP recommending a screening colonoscopy and they are paranoid. So, poll the audience.
And yes, my day is coming soon enough.
