Original Title: Study found that people who were not married were less at risk (at least 50% lower risk) than married people for dementia. One contributing factor may be that single people are better at maintaining social ties. Single people may also have a greater variety of interesting and unique experiences.
Selection bias…
A frightening amount of people get married because they’re worried about having someone to take care of them at an elderly age. Even if their goal is recipical, for a lot of people that’s a big driver for marriage.
People who are more self sufficient and with a strong family health history doesn’t have that drive.
Couple that with not being able to “offload” tasks to a spouse and you end up with single people staying active mentally which is one of the biggest negative correlations to Alzheimer’s.
