Life expectancy at birth increased from 32 years in 1900 to 73 by 2019.
In high-income countries, most improvements are in mortality rates after 70 years of age.
Chance reaching 90, has gone from a 1 in 100 long shot to a 1 in 3 probability.
This means more people are living to ages where their health is getting worse.
Disease burden has shifted from infectious diseases towards non-communicable diseases.
A health intervention that lowered mortality at every age, increasing life expectancy by one year, would be worth $37 trillion in the US.
The most valuable health priority of all is to ensure that healthspan rises to match lifespan.
It will require the development of treatments which target ageing itself.
Researchers have proven that age reversal is possible in mouse and human cells.
Treatments that delay ageing are highly beneficial because they lessen the probability of disease.
