@jolam PLEASE do some research on the full sedation. I've had several Colonoscopies (now I do Cologard) and have noticed a mental decline afterward that did not go away. Two yrs later, I continue to have word recall probs. Recently there have been studies on this and MAYO Clinic did the most recent one that I saw; they confirm that mental decline happens in people over 70 who've been under anesthetic! (I believe it was propofol + fentanyl that was given to me for the Colonoscopies. The Docs pooh-poohed my suggestion about having some mental slow-down afterward.)
