That leads to the outcome that your statement "The science of keeping humans healthy is fairly well researched" is false.

Actually it is the least researched field among the most important, in my humble opinion.

No, it doesn’t. Because the study of health and the being of health are separate topics entirely.

> the study of health and the being of health are separate topics entirely

I would rather say that your statements in this particular topic and wise statements per se are separate things entirely and what you have just claimed is not at all.

I'm not sure what you mean exactly by this, but I think I understand a little. The reason why the study of health is separate than the being of health is that the being requires time and experience. I cannot convey how I feel when I eat clean, lift well, read a lot, and socialize often, but I can say that I feel "happy" or "good" and give you a list of steps to achieve that state.

This essence of "lossy transmission" is simply our reality.

A lot of people either seem to not understand that science is focused on testable models of phenomenon and not the actual phenomenon itself, or they refuse to believe any such meaningful distinction exists.
