You have it backwards. The pot smoking Indians were sold fire-water and made to eat cooked meat by the drunken Eurpoeans.
I am siding with Raw Kyle.
My dad was just about bald in his 20s. I am 57 and my GF says my hair is starting to grow back lately. I have much more hair than him. I am a 23 year veteran of vege diet. Only thing that has changed is RPD and Aajonus Vonderplanitz suggestion of raspberries/cream/honey/coconut before bed which also stops my snoring.
My hair started falling out when I left home and went from drinking pasteurized skim milk at home (yuk) to drinking lots of pasteurized whole milk. Other issues started then but that's another story. Raw milk is fine. I am not suggesting raw milk is the answer BTW, it just works for me.
BTW my exes dad used to rub his fingernails together and he claimed it made his hair grow back. He went from shiny to hair regrowth. Go figure that one out.
The aboriginal North Americans were well known to be very healthy, tall, strong, have beautiful features and beautiful hair and no beards. This is based on the reports of the early explorers. The fact that most of them were wiped out by European diseases skews the subsequent study of them. Initial estimates of the population of NA was around 1/2 million at the time of European contact, but subsequent study shows the # at 75 million and climbing.
So the people in any photos of ANA would be the survivors of the onslaught of white man's diseases and therefore their appearances would not be reflective of the majority of their ancestors.
Ayurveda says that salt consumption will cause gray hair. Long explanation.
I have a theory on baldness which I will save for another post, but as I said I am with Kyle in the diet as causal root. (no pun intended)
