Ed,
It's not until the western medicine took hold in most of the world that the life expectancy increased dramatically.
Even in europe during the dark ages they practiced cranial bleeding to cure diseases. Voodoo!
All these "voodoo" techniques have been practiced in many places in the world, China, Papua New Guinea, Borneo, Amazon, Africa for thousands of years.
A lot of superstition and "feel good" marketing. All ganja man!
There is value in natural cures, but a lot of it is overblown.
"China has a history of around 5000 years."
That doesn't mean anything. People have lived in most of continental Euroasia for 40,000 years.
Africa has history of over 100,000 years and it's still all voodoo.
I will give China credit for perfecting combat techniques, but medicine no.
Voodoo!
It's time to leave the voodoo behind and get with the science of the times.
