Prevention is a wonderful word that is too little appreciated by people in North America and many other countries. Just look at recent news.Prevention applies to mega forest fires (controlled burns in advance), earthquakes (better construction in California than Iran saved lives during similar levels of earth tremors), and many diseases.
Unfortunately,
medical - pharmacology complex finds it far more profitable to treat diseases with pills and "procedures" (surgery), than to prevent them with good diet and lifestyle practices.
Unfortunately, most of us prefer magic cures to taking responsibility for our own health.
What is far worse is that many tests and surgeries are popular, but actually do little for overall longevity.
Examples:
CHOLESTEROL level in blood is easy to test, but is not
whole story for heart attack and stroke. But pill pushers love to sell drugs to reduce cholesterol levels.
