When Friedman and his associates analyzed the Terman Life-Cycle Study to find the personality characteristics that predict long life, they found a link between conscientiousness and longevity.

The Terman Life-Cycle Study also known as Genetic Studies of Genius is a study in the field of psychology that is considered to be the longest study that repeatedly followed individuals throughout their lives from childhood through death. This study was started by Lewis Terman. In the study conducted by Friedman and his associates, Howard S. Friedman’s suggested that conscientious individuals live longer.

the arab empire adopted the muslim religion as their main belief. arabs would influence the people from the territories they invaded towards islam (the muslim belief).

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.
