Final answer:
The study about Catholic nuns writing autobiographies at age 22 found those expressing happiness and positive feelings lived an average of 7 years longer. This reflects broader research that positive emotions and a sense of community, purpose, and coping abilities are favorable for longevity.
Step-by-step explanation:
A study of Catholic nuns who were asked to write a brief autobiography at age 22 revealed that those who expressed happiness, love, and other positive feelings lived an average of 7 years longer. This finding aligns with other research indicating the impact of positive emotions and self-perceptions on longevity. Insights from such studies suggest that having a positive outlook can contribute to a longer life. Aspects like a strong sense of community, feeling a sense of belonging, and having a sense of purpose (for example, through work or group affiliations) can be significant to one's wellbeing and potentially influence lifespan.
Furthermore, the ability to cope with life's challenges, such as the loss of a loved one or facing one's own mortality, is often better handled by those with a positive emotional state and social support systems. Elements of spirituality, social connectedness, and maintaining a sense of identity throughout different life phases, as proposed by theorists like Erik Erikson, contribute to the overall emotional wellbeing and could play a role in healthy aging.
