In [1], it states that:
On average, women live longer than men. In fact, 57% of all those ages 65 and older are female. By age 85, 67% are women. The average lifespan is about 5 years longer for women than men in the U.S., and about 7 years longer worldwide.
There are many reasons why the ratio of men to women (which is roughly equal in young adulthood) starts to favor women over time. Among the most powerful factors? Dr Robert H. Shmerling said that men tend to:
Take bigger risks
Women are more likely to follow COVID-19 safety measures, study shows[9]
Have more dangerous jobs
Die of heart disease more often and at a younger age
Be larger than women
Across many species, larger animals tend to die younger than smaller ones. Although the magnitude of this effect is uncertain in humans, it may work against male longevity.
Commit suicide more often than women
Be less socially connected
Women are good about sharing feelings, whereas men often form relationships around activities like sports, hobbies and business interests. Men rarely sit down with a buddy and simply talk about their feelings or on the condition of their personal lives.
Avoid doctors
Produce a less powerful immune response than do women
Men showed much weaker activation of T cells, and that lag was linked to how sick the men became in a Coronavirus Study. The older the men, the weaker their T cell responses.
The gene expression pattern that controls innate immune responses to viral infections begins to decrease dramatically in men between the ages of 62 and 64. In women, this immune response begins to wane about six years later in life.[12]
Women mount faster and stronger immune responses, perhaps because their bodies are rigged to fight pathogens that threaten unborn or newborn children.[6,10]
The New Coronavirus Appears To Take A Greater Toll On Men Than On Women
Sex differential in COVID-19 mortality varies markedly by age
Sex differences in immune responses that underlie COVID-19 disease outcomes
Over all, the scientists found, the women’s bodies produced more so-called T cells, which can kill virus-infected cells and stop the infection from spreading.

Sex differences in COVID-19 immune responses affect patient outcomes
Immune system variation can predict severe COVID-19 outcomes
