Tbh, there's probably some scientific validity to the bias towards female sex towards the extreme margins of age when trying to assess survivability.
It's commonly accepted that the protective effects of natural estrogen delay age-related heart disease by about 10 years in women (ie. Heart disease in women mostly begins after menopause and its risk level is roughly equivalent to a male ten years younger.)
The statistics in retirement homes and nursing homes are also ridiculously skewed towards women. At a certain age, occupancy by sex ratio often approaches 7-11:1.
There's also an age cutoff (?90), where women outnumber men something like 10:1 and the ones still living statistically almost all involved exhibit some degree of cognitive decline.
Just spit-balling here but is there any correlation between women leading more risk-adverse lives and therefore having a long life-expectancy?
IE men are more likely to excessively drink/smoke/eat earlier on in life or lead more physically demanding lives and pay for it with a overall shorter life-expectancy?
The life expectancy gap is certainly multifactorial.
Part of it is men working more dangerous jobs and dying at work or suffering injury from the same.
Some of it is probably men more likely to be involved in violent crime or be a victim of violent crime.
Some of it may be related to addictions like tobacco/alcohol/opioids. Though, IIRC, past generations with a higher percentage of men smoking have become much more egalitarian in terms of smoking rates between sexes in modern times.
However, some of it comes down to basic biology. A male's reproductive role is generally finished upon conception and thus there's less evolutionary pressure to keep men alive.
As previously mentioned, women have endogenous protective factors such as estrogen for heart health and possibly mitigation of dementia risk that males simply don't have.
Finally, on the chromosomal level, men get screwed. Women naturally have protection against any sex-chromosome linked diseases since they have two X chromosomes. If they suffer a single gene mutation resulting in a defective gene on one X chromosome, they likely won't suffer any ill effects of a genetic disease if it is recessive since they still have one functioning gene on the other X chromosome to protect them.
Men are not so lucky, as their Y chromosome is more-or-less nonfunctional, so they rely on the single functional copies of sex-linked genes on their X chromosome.
But if there are any single gene mutations in their single copy X chromosome DNA, they will suffer from the related disease.
This is why some diseases linked to sex chromosomes are almost exclusively seen in men.
