I have an elderly relative with no children, who phones me with increasing frequency, as she gets older. She has always been a "people person" and has boasted that she can talk to anyone, of any background, which is true. She has always been ready to do anything for anyone, and spend time talking to anyone who is troubled or alone.
Trouble is, since Covid her contact with others has diminished and she is full of talk but little opportunity to share it, so when she starts to chat she doesn't pause. She can start on something that happened to her, go on to telling me the life history of someone who was present when that happened, move on to an account of each of that person's family, then relate the medical history of one of the family, followed by how how own husband had that same illness and his experiences in hospital, and what medication he was given, which leads her on to the medication she had for some ailment and the side effects it gave her, and her difficulties in getting a GP appointment to get it changed. And so on for (on one occasion) an hour and twenty-five minutes (I timed it) with me saying no more than an occasional "Mmmm" or "Oh dear".
If people would tell you one thing about themselves and then pause so that you can tell them something equally boring about you then all things would be equal and we wouldn't get so frustrated at having to be patient while someone drones on about every detail of their not-very-interesting life.
I suspect that with age and/or illness a kind of desperation sets in and they feel that they may not have the time left to them to do all the communicating that they would like to. However, it is self-defeating, because they end up with less attention instead of more if they keep talking too long in an attempt to hold the hearers' attention and hog the limelight like a fading movie star trying to look glamorous. The hearers don't interrupt out of politeness and consideration, but feel put-upon - perhaps they would be better to be honest and jump into the least pause for breath with a pre-prepared conversation-turner?
