What is the Secret to Longevity and Happiness?

A study known as the Harvard Happiness Study, which has been running for over 80 years addressed the following questions: What contributes most to a person’s happiness? What is the most common regret people have near the end of their lives?

While we don’t necessarily need modern research to prove what we’ve known for thousands of years: “It is a tree of life to those who grasp it, and its supporters are happy”, that one who truly lives by the Torah’s ways merits joy and long life- but it’s always powerful to see that scientific research confirms timeless truths.

What is This Study About?

The study began in 1938 at Harvard University and tracked the lives of a group of young men for over 75 years. It followed 724 men from various socioeconomic backgrounds—some Harvard students and others from Boston’s working-class neighborhoods.

Over the years, researchers collected extensive data about the participants physical and mental health, careers, relationships, and lifestyle choices. They conducted interviews, medical exams, and even visited the participants homes, gaining deep insights into the factors that influence happiness, health, and longevity.

Not What You’d Expect

Western culture often equates personal success with wealth and material achievement, promoting the idea that money and possessions are the key to happiness and fulfillment, but the results of the Harvard study took many by surprise and made headlines worldwide. Nearly 80 years of research debunked the widespread Western narrative and brought attention back to life’s fundamental values.

According to the study, several factors contribute to happiness and longevity, but one stood out above all: Strong social relationships.

Otherwise known as, a life rooted in community. The study found that strong relationships are the most important factor for both happiness and good health. People with close social connections tend to be happier, healthier, and live longer than those who are socially isolated. And quality matters more than quantity—it’s not how many friends you have, but how deep and supportive those connections are.

For us, this is no surprise. We’re well familiar with the saying "Either companionship or death" (Taanit) and the Mishnah in Pirkei Avot which teaches: “Acquire for yourself a friend.” Maimonides (Rambam) also emphasizes that a person naturally follows the views and behavior of their companions and society. Therefore, one must remain connected to the righteous and wise to learn from their ways.

Other Key Findings From the Study

1. Community Involvement: Active participation in community life is crucial for mental well-being. Those who engage with their community feel less lonely and are generally happier. Jewish life is rich in community experiences including synagogue prayers, Torah study in the beit midrash, and shared celebrations and mourning. From birth (bris, kiddush) to death (funeral, shiva), every significant moment is experienced within the framework of a community, placing the individual in a central and meaningful role.

2. Optimism, Forgiveness, and Generosity: Optimistic people tend to cope better with life’s challenges and experience more positive emotions. The study shows that a positive outlook boosts the immune system, lowers stress, and promotes healthier choices. The ability to forgive and let go of grudges, as well as a spirit of generosity and giving, are common traits among those who live long and fulfilling lives.

3. A Sense of Purpose: Finding meaning in life contributes significantly to longevity. A sense of purpose can come from work, close relationships, hobbies, or religious faith. King Solomon said it best: “After all is said and done: fear G-d and keep His commandments, for this is the whole of man.” (Ecclesiastes) Closeness to G-d and observance of His commandments provide the deepest and most enduring sense of purpose in life.

Another fascinating aspect of the study explored people’s regrets near the end of life. When participants were asked about their biggest regrets, the responses were eye-opening. Very few said they regretted not making more money, and most spoke of family and values:

Not spending enough time with loved ones: Many regretted not dedicating more time to their family and close friends.

Not pursuing their dreams: Several wished they had taken more risks to fulfill personal goals and ambitions.

Working too much: Some regretted prioritizing work over meaningful time with loved ones.

Neglecting their health: Many admitted they should have taken better care of their physical and emotional health.

Not expressing emotions: A number of participants regretted not being more open about their feelings with others.

Happiness and joy are universal values across all cultures. Judaism teaches that true joy comes from deep relationships with family, with community, and above all, with G-d. The Harvard Happiness Study affirms what the Torah has taught all along.

"Blessed are You, Hashem, who gave us the Torah of truth and implanted eternal life within us.”
