I will highlight one key to what you wrote: "However, just like all diseases, people vary in their susceptibility." I agree as each person can be different. Their immune system can be different. I agree that prevention can prevent the need for correction later on. People should focus more on prevention over correction for their health. In the past two hundred years or so, that paradigm reversed towards correction over prevention for many people. That is too bad. So, education is key in helping people understand some basis principles, some eternal fundamentals, to common sense.
