Why does nobody read articles before weighing in?

They discuss this and discount it in the opening paragraphs.

One might be tempted to explain the disparity as a natural consequence of women living longer. But those studying the disease say that wouldn’t account for such a large difference, and they’re not precisely sure what would.

While many factors may be at play, researchers are zeroing in on two where the biological differences between women and men are clear: chromosomes and menopause

Any competent statistical/scientific study will account for obvious population disparities.

My theory: make up? Usually these things tend to be because group A is commonly using or doing something that group B is not.

There are multiple possibilities.

• The “man flu” phenomenon whereby a man with a minor illness is more likely to take a day off and rest while a woman with a minor illness is more likely to power through, with the lack of rest resulting in more neural plaque buildup

• Some unexplored link between dementia and clinical depression, whereby the men most susceptible to depression are more likely to kill themselves in their youth and thus leave the elderly male population less susceptible to dementia overall

• Men (at least in the generations that have reached old age) were more likely to cultivate hobbies in their youth which keep their minds active in old age whereas women were more likely to focus on friends and family who are less available as the years pass
