Quote:
One of our group, Dr. K. Biss, served in a “mobile hospital” (a medically equipped Volkswagen) in Masailand as a volunteer physician under the sponsorship of the Ministry of Health of Kenya during 1965.
He was then fully aware of the low serum cholesterol levels and total absence of atherosclerotic coronary heart disease among the Masai,
in spite of their unusual but customary diet composed entirely of animal fat, carbohydrates, and proteins, as first reported by
Mann et al. (3).
Mann, Shaffer and Rich believed that this might be due to freedom from emotional stress and an abundance of physical exercise. However, Dr. Biss was not entirely satisfied by this explanation. He was especially impressed by the fact that the physically active part of a male Masai’s life is over
when he completes his warrior period and marries, usually by the age of 24. After this, his wife or wives perform most of the work. Upon Dr. Biss’ return to the United States, a team was formed to explore this mystery
further.

If we accept the above, exercise might explain why the Masai had less plaque during the warrior period... but not why their atherosclerosis in later years didn't come with life-shortening heart disease.
Perhaps early atherosclerosis (warrior age) is particularly bad for the artery remodelling needed to properly sustain the adult body? Wild speculation here.
