Here's an interesting article.
https://edition-m.cnn.com/2018/11/06/health/genetics-longevity-study/index.html?r=https%3A%2F%2Fedition.cnn.com%2F
Many of my researched ancestors did well, but two of my grandparents only got to 65, while the other two got to over 85. Now in my early 60s, this article cheered me up.

I think the whole basis of the research is questionable.
Fatal accidents shouldn't come into it at all - pure chance, unless we're straying into Final Destination country!
Both my grandfathers died relatively young but I put that down to what they endured during WW1. Neither was killed during the war but one was badly gassed and the other suffered a facial gunshot wound.
My great grandmother died of anaemia after childbirth - at a ridiculously early age. That just wouldn't happen now. And what about all those poor women over the ages who have died in childbirth, and the poor men who died in battle?
I'm sure a small amount of attention has to be paid to inherited genes which might make a family more susceptible to a specific disease but mostly, I think its down to nurture, environment and pure happenstance.

Also suspect if, as suggested, research was based on Ancestry pedigrees indicating longevity in families. Well we all know how spurious some of these trees are, and who is to say if each pedigree they used was actually genetically related - about from the spurious info that some contain there might also be several with non-paternal events.

Looks this was the basic plan....

And as was already mentioned, there are problems with trees. Wonder how they anonymized them.

So ancestry have released some info. from all the trees they have to a company totally funded by Google.
I am glad my tree is not there and I use Google as little as possible.

They are interesting comments. We've heard of the 'born in 1795 and marrying in 1910' stories. They must skew the stats.

Ignoring the Ancestry and looking at the genetics there is some basis to 'long living genes'
There is a family in South Australia - The Fuss Family - that have been regularly reported on as long livers.
There is also a Nobel Prize to the team that discovered and analysed telomerase particles that have a function in aging

Statisticians say that we die sometime between the ages our parents died.
My billy Blue was 99 when he died; my dad, his g-g-grandson, was 101 when he died.
Maybe just coincidence.
When I was trying to get a mortgage, the insurance guy at first refused because I was over 60.
Then he asked my parents' ages when they died - when I said almost 88 (mum) and 101, he said 'Sign here. You'll probably live till you're 90.'
So at least the insurance companies must believe in the theory ::) ::) ::)

If that happened regularly wouldn't that mean that as generations go on, they would be dying younger and not living longer? ;D
GGGG grandparents die at 70 and 80 so son dies at 75
GGG grandparents die at 65 and 75 so son dies at 70
GG grandparents die at 60 and 70 so son dies at 65
GP die at 55 and 65 so son dies at 60
Parents die at 50 and 60 so you die at 55.

So I have 11 years left.

My mother has already outlived both of her parents, both of whom died of natural causes. With improved medical care over the years and fewer people smoking than in decades past, I imagine outliving your parents is not unusual.

My dad was 48 when he died. The last of his 6 children has just turned 49. What we didn't know was that he had rickets as a child, hence his early death. His parents were 84 and 85 when they died.

I always tell my grandchildren that when my grandmothers were my age they were both dead!!
My maternal gran died aged 72 of a cerebral haemorrhage having had hypertension most of her life, whereas I have very low blood pressure. My paternal gran died aged 66 of cancer of the pancreas and I hope I never get that. Both my grandparents died when my parents were young. My paternal grandfather was killed in a motorcycle accident in 1926 when my dad was 14 and my maternal grandfather died of TB in 1922 when my mum was 11. However, my father died aged almost 92 and my mother aged almost 96 and I'm hoping to outlive both of them.

You can never tell. In my wider family going back to 1695 there have been some very long livers, like died 97 in 1757. Then again not a few who died in their early 40's.
Heard an interesting article on Radio4 Today recently. 64 is the expected life expectancy in good health. Thereafter declining health. I was lucky, I started to go downhill at 72. Modern medical science can keep people alive much longer than 64, but that's existence, not life.

I have outlived my parents, my grandparents and my great grandparents.
Must be that low cholesterol low sugar diet the result of rationing in my childhood.
