It is NOT the same cycle. Every life is different. So what the people learned 500 years ago made sense for them - but they would face a hard time now. Our knowledge of daily living will be mostly obsolete in 200 (or much less) years, too.

Fresh minds don't have the burden of outdated ideas... quoting Max Planck: "a new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it."
