The people in mud huts didn't even get sick until modern death culture cornered them and perverted their sustainable cultures.

You do what you want but I'll use the free natural remedies that kept our species rolling and evolving for hundreds of thousands of years over the poison that keeps modern civi zombies taking pill after pill just to live long lives as dependent slaves that feel like shit most of the time or are too numb to know if anything's wrong.

Hit me up in ten years and we can have a physical challenge. I will win. ;)
