Basically adults 100 years ago and more had very different lives and doing hard labor and various things to survive day to day made them into something that is different that what the average adult is today. So many men today have low testosterone and basically act like women. Many women are very immature and emotional beyond even the normal amount that women should normally be based on sex differences. Even many people who exercise a lot and are in good shape would have a complete breakdown if they had to so much as survive sleeping in their car overnight or something.
We are essentially a society of domesticated beings rather than free natural humans. I include myself in this as well as I'm obviously a product of this sick society but have been working for years now to push myself well out of my comfort zone.
100 years ago the labor required to live was higher. More physical exertion resulted in higher testosterone scores (with no plastic to bring it down). Women were just as sheltered and ignorant as today, but they likely did better in school than now- if they went at all. They just didn’t have the same type of pop culture, their social circles revolved around their communities and homes. But they were still quite uneducated, and doctors used to treat overemotional and “hysterical” woman as a specialty.
People were tougher, but many perished in the same stupid ways as today. Many more alcohol related deaths occurred, especially in cold places where an ejected patron might fall asleep in a snow bank. Bums lived a semi-rural life instead of congregating around urban drug houses. But really, an adult had the teaching of the church alone to guide them at that time, so their lives were directed by doctrine as opposed to thought, but this began to change with WW2
