Married men have something more powerful and consistent than frequent sex. They live with at least one person who cares about them and looks out for their welfare. In general, women are wired to detect and act on less acute problems.

There’s a bell curve for frequency of sex among couples, but far more consistent is a spouse encouraging her husband to go to the doctor.

I worked on a project years ago that was pretty disturbingly accurate at predicting health outcomes by looking at behavior. The most at risk for anything were divorced males, even more than alcohol or drug abuse. Basically that event makes a wide variety of bad outcomes more likely. They are also east to spot and market to with destructive products ranging from alcohol to gambling, you name it.

For women it was different, the caretaking trap was a major risk factor for health issues - the catalyst was often a sick parent.
