Unfortunately the inuit appears to have evidence of commonly having heart disease even in the 1940s and of course the mummified remains of 2000 year old inuit corpses show arthrosclerosis. So it appears not only a modern issue but it has alwaya been an injit problem which would explode the myth of inuit invulnerability to heart disease as being something arrived at erroneously by anti ancel keys people?
On the masai, it is apparently true that there is high infant mortality though reporting of death is complicated by the masai social custom of not mentioning rhe dead. However aa this study shows l, the story on mortality doesn’t end there because adult mortality is also very high as well. Among others they have very high rates if mothers dying in childbirth, among the worlds highest hiv infectioj rates due to their serial promiscuity and the dangers of their pastoral lifestyle such as stepping on land mines! So it appears that the 42 to 45 year mortality rate is not caused just by infant mortality rate but by adults dying too early as well…

The same poor and inaccuratereporting of death would also constain and loqer the rate of accurate report of death due to heart attacks etc. Anyway whatever it is about the masai that causes them to have lower reported rates of each due to heart disease despite having much evidenceof arthrosclerosis, is it translatable to other people of other cultures and ethnicities? Either it is due to their extremely high levels of moderate cardiovascular exercise of walking 19 km a day more than modern Americans m (which BTW is similar to Mediterranean shepherds in blue zone lifestyles) or it is due tl a genetic adaptaiton due to their diet iver thousands of years, it is not able to be reproduced and enjoyed by others…
