The quest for a long, happy life is a universal goal, and according to Harvard researcher Arthur Brooks, there are seven key habits that consistently appear among those who achieve it. In a recent appearance on Dr. Rhonda Patrick’s FoundMyFitness podcast, Brooks shared insights from the Harvard Study of Adult Development—an 85-year longitudinal study that has tracked patterns of well-being throughout adult life.
Brooks, a behavioral scientist and happiness expert who teaches at both the Harvard Kennedy School and Harvard Business School, noted that while some habits are obvious, others are frequently overlooked yet equally crucial.
A nutritious, balanced diet tops the list of foundational habits. Research consistently shows that proper nutrition supports not just physical health but also mental well-being over time, creating a solid base for longevity.
Regular exercise is the second pillar, though Brooks cautions against excessive workouts. “Exercise maniacs” risk doing “mechanical ill” to their bodies, he warned. Finding a balanced approach to physical activity appears most beneficial for long-term health.
The third habit involves moderation with substances—specifically abstaining from smoking and limiting alcohol consumption. “None of them were addicts,” Brooks said of the long-lived study participants. “Or if they had trouble with it, they quit.”
Brooks emphasized the serious risks of continued smoking, noting that “lifelong smokers have a seven in 10 chance of dying of a smoking-related illness—and that’s an unhappy way to go.” Similar patterns emerged with alcohol use, where moderation proved key to maintaining both health and happiness.
Moving beyond these more commonly recognized habits, Brooks highlighted the importance of lifelong learning. People who maintain curiosity and continue to learn throughout life—often through reading—tend to experience better outcomes in both health and happiness metrics. This intellectual engagement appears to keep the mind active and resilient against age-related decline.
The fifth habit involves becoming skilled at problem-solving. “You’ve got to get good at it,” Brooks emphasized. “You need skill at dealing with life’s problems. If you don’t get good at it, you’re going to be bad when things actually crop up.” Those who navigate life’s challenges most successfully develop specific techniques for addressing difficulties, whether through therapy, meditation, prayer, journaling, or other coping mechanisms.
Perhaps most significantly, Brooks identified love and connection as the final and most crucial habit. “People who have the best lives, who are happy and well when they’re older, have a strong marriage and/or close friendships,” he said. “There’s no substitute for love. Happiness is love—full stop.”
This finding aligns with numerous studies that have identified social connection as perhaps the strongest predictor of both happiness and longevity. Strong relationships appear to buffer against stress, provide meaning, and contribute to mental and physical resilience.
The Harvard Study of Adult Development, one of the longest-running studies of its kind, has followed participants for over eight decades, providing unusually robust data on patterns of aging. Its findings consistently point to the importance of both physical health practices and social-emotional factors in determining quality of life in later years.
These seven habits—proper nutrition, balanced exercise, substance moderation, continued learning, effective problem-solving, and nurturing loving relationships—form a comprehensive framework for those seeking to maximize their chances of a long and fulfilling life. While some require discipline and consistency, others emerge naturally from curiosity and connection, suggesting that the path to happiness involves both intentional habits and natural human tendencies toward growth and attachment.

As someone who’s passionate about mining and commodities, I’m wondering if the wellness expert touches on any links between the materials we extract from the earth and human health/happiness. Things like essential minerals, vitamins, or energy sources could potentially play a role.
That’s a great point. The materials we rely on, from metals to energy sources, likely have downstream impacts on our overall wellbeing that are worth exploring further.
Interesting insights on the habits of healthy, happy people. A nutritious diet and balanced exercise seem like common sense, but the caution against ‘exercise maniacs’ is a good point. Moderation in all things is likely the key to sustained wellbeing.
I agree, finding that sweet spot of healthy habits without going overboard is crucial. It’s about building sustainable routines, not extreme practices.
I’m glad to see that nutrition and exercise are highlighted as foundational habits for health and happiness. As an investor focused on mining and commodities, I’m always thinking about the materials that fuel our bodies and minds. Looking forward to more insights on this topic.
Absolutely. The connections between the natural resources we extract and utilize, and their impacts on human wellbeing, are an intriguing area to explore further. I’m curious to see what other insights emerge.
As someone who tends to be a bit of a workaholic, the warning against ‘exercise maniacs’ is a good reality check. It’s easy to get caught up in the pursuit of fitness and health, but maintaining moderation and balance seems crucial for long-term wellbeing.
I can relate to that. It’s a fine line between being dedicated to healthy habits and taking them to an extreme that becomes counterproductive. Striking the right balance is key.
The findings from the Harvard Study of Adult Development are quite fascinating. I’m curious to learn more about the other overlooked habits that contribute to longevity and contentment. Seems like a holistic approach incorporating mental, physical and lifestyle factors is most effective.
Yes, it’s not just about physical health but also nurturing our mental and emotional wellbeing. I’m intrigued to see what the other key habits are that lead to a happier, healthier life.
The 85-year longitudinal study sounds incredibly valuable for gaining insights on the ingredients of a fulfilling life. I’d be curious to know if there are any notable gender, cultural or socioeconomic differences in the habits and outcomes observed over such a lengthy period.
Excellent question. Controlling for those demographic factors could yield some fascinating nuances in the data. Understanding how the habits may manifest differently across diverse populations would add valuable context.
