How do old people die?

How do most old people die?
We've just lost one parent to cancer, swiftly thankfully. Hospitalised then at home for the last few weeks.
The in-laws are suddenly looking old. FIL gets a bit muddled with names and frankly smells of wee in a way that would have embarrassed him just two years ago.
MIL is holding together but snapped when hosting at Xmas and said she was never going to do that again.
Anyone got a crystal ball? What can we expect over the next few years.

I'm shocked to. But that's the in-laws, none of them talk or admit they are open to change or float the possibility of change.

We turned up after Xmas to find they had put on the table something like 37 plates of food over the previous three weeks with multiple bed changes for various combinations of siblings and grandchildren.
So that's planned, shopped, cooked and cleared away. All excused by she likes it, or she'll be pleased to see us.
(MIL counted)

We minimised our stay and took them out for a pub roast. They looked broken.

I've been trying to get some of the older generation in my family doing some different things at Christmas in the hope that it's not as upsetting when they reach a point where they can no longer host. We've also got a sad story with an elderly family member spending the first Christmas she was unable to host sobbing in a pub.

We were ‘lucky’ - she suddenly went downhill just 10 days before the entire family was going to be away for at least a week, for DD’s big wedding do in France. It was all over within 36 hours and one of us was able to sit with her the whole time - not that she was apparently aware of anything, and hadn’t known us for a few years.

TBH although sad in a way, it was more of a relief all round - we were all too conscious of how much her former, intensely private self, would have hated how she’d ended up.

Heartfelt sympathy to you, it’s all such a horrible worry.

They usually come into hospital following a collapse after stroke, heart attack or some kind of organ failure. Or a fall after say a urinary tract infection. Quite often leading to pneumonia due to immobile.
It's really important for them to fill out a TEP (treatment escalation plan) with the GP so their final wishes can be respected if they get sick. I have one and I'm 62.

I think my FIL's treatment escalation plan would be:
Call consultant he used to play cricket with
Call anyone who may have treated the royal family
Research cloning and cryogenics
Assume starfish position so they can't put him in a box.

MIL will creep away, lie down under the redcurrent bush and slip away.

My heart goes out to all of you who have supported people on the slippery slope to goodbye.
