These longevity factors common among healthy ninety-year-olds are based on the findings of the project by Harry Mouratidis, M.Sc. This project, which appears in the book They Live Longer, written by Harry Mouratidis and Dr. George Price, concentrated on ten 'longevity villages' in Spain, France, Italy, and Greece. You might find that some of these factors, which are shown in the Longevity Pyramid, are not well publicized.

Readers are encouraged to consider, discuss, or modify the pyramid contents drawing upon their own experiences, opinions, knowledge, and expertise.
