The reality is that overall life expectancy is much higher now than when your great great grans was alive thanks to modern medicine. The goal should be to move more, eat more nutrient dense foods, and build healthy relationships to maximize your quality of life as you age. No need for extreme diets or lifestyles in order to age well.

After 2020 and recent loved ones health system experiences I seek to avoid all contact with the modern healthcare system, unless its a life or death matter.
I see ancestral foods as a way and thing I have full control over to avoid avoidable sickness.
I’m sorry that you and your loved had such a negative experience. I agree that lifestyle choices are an important part of health, but for me, keeping up with recommended health screenings is a necessity too, so I made sure to find a primary care provider that I felt respected me and was knowledgeable.
