The most important thing I learned from this book is that everyone has a preset approach to modern medicine. Some people try to avoid medical interventions and and sort of 'go back to nature'. Some people rely on the latest technology and want to maximize every scientific treatment available for their health.
Neither extreme approach is wrong! Our unique approach to medicine is highly individual. Our level of trust in the medical system is based on how we were raised and what we learned about modern medicine as we grew up.
Trying to convert you to my personal approach may go against your intrinsic beliefs. 'Going back to nature' may be what is right for me, but it may scare the heck out of you! If you adopt any extreme approach without complete belief in it, you might have a bad outcome and suffer intense regret.
My takeaway: Be forgiving of other people's approach to modern medicine.
