A new book from a renowned Harvard University doctor reveals why being happy is an even better predictor of a long life than your cholesterol levels are. Plus, his most shocking scientific discovery about how to become happy—all based on 100 years of Harvard health data.

Building and maintaining strong, supportive relationships by age 50 is the key factor that contributes to better health and well-being at age 80.

Key​

  1. Harvard Study of Adult Development: This long-term study has shown that the happiest and healthiest individuals at age 80 were those who had satisfying relationships at age 50. The quality of these relationships, rather than wealth or achievements, was the most significant predictor of health in later years.

  2. Impact of Relationships: Good relationships not only enhance happiness but also protect physical and mental health. Participants who reported high satisfaction in their relationships experienced lower risks of heart disease, cognitive decline, and mental health issues.

  3. Social Connections Matter: The study emphasizes that it’s not the quantity of relationships that matters, but the quality. Individuals who felt cared for and connected to others were more likely to thrive as they aged.


    In summary, prioritizing and nurturing relationships by the age of 50 can lead to a healthier, happier life at 80.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
