Maximum life and health has increased and not comparing to the bottom half

There is book that looks at Aging in the Past

Up until 1900, less than 10% would make it past 80.
Among the population those over 60 were less than 10% of the population. People had more kids and lived shorter lives.

Lagging survival based on the age people die in a year. How old were people when they died in 1991

What are the Ages that British Actuaries think Brits will die

There is a statistical analysis of when people born in different years might die

So people born in 1900, had a 10% chance make it to 1991.
But people born in 1991 are expected to have a 20% chance make it 100 according to statistical trends in improving longevity.
There is more of a chance that people should make it 100 than did it make it to 91.

Also, some sources claim that there has been “no improvement in maximum human lifespan”.
There is a lot of difference between 10% of the people making it to 90 and 0.1% making it to 90.
There were 92 million people in the US in 1910. There are now 55000 centenarians in the US.
So 0.06% made it to 100.

The Oldest verified female made to 122 and the oldest verified man to 116.

A Bolivian man with inferior documentation might have lived to 123.

But 1 in a billion is not something to plan on or we would buy Powerball tickets as part of our retirement plans.

Almost 40% of Swedish females born in 1920 made it to 2010

Here is another source of analysis of survival curves

Japanese women live four years longer than american and british

You should ignore the bottom half of the survival rates if you
* not poor
* never smoked
* not sedentary
* do not drink to excess
* do not have diabetes

Use the forward looking estimates.

So by not doing stupid things to shorten life then 100 becomes a lot more possible and reasonable.

For chances at really big lifespan improvement then provide support to the research that is targeted at that goal.
