The effectiveness of Modern medicine operates on a spectrum. They are fantastic at dealing with trauma and emergency, while being near useless, and often detrimental, in dealing with " diseases of modernity" such as heart disease, cancer, diabetes, obesity, neuropathology, and especially, malnutrition.
After a lifetime of chronic disease, I personally have taken responsibility for my own health and reversed over 25 chronic, often debilitating conditions over the last 14 years. None of these were effectively treated by the many medical specialists I had consulted in the decades prior. Many were well meaning, but woefully unequipped in understanding the healthy and fit functioning and care of the human species.
Enjoying the best fitness and health of my life, physician-free, in my late sixties.
