Not smoking or abusing alcohol, Healthy weight and exercise, Mature adaptations and quality education, Stable marriage at age 50 were linked to reaching 80 in a good place according to Vaillant.
Vaillant had discovered seven major factors that predict healthy aging, both mentally and physically.
One example was the use of mature adaptations. Education, a stable marriage, not smoking, not drinking excessively, some exercise, and a healthy weight were the others. Half of the 106 Harvard men who just had five or six of these variables in their favor at 50 ended up as "happy-well" and only 7.5 percent as "sad-sick."
Meanwhile, none of the men who had 3 or lesser of the aspects of health at the age of 50 were "happy-well" at the age of 80.
