What Keeps Us Healthy and Happy in Life?

Introduction

Key question: Investment in future well-being?
Survey insights:
- Millennials' top goals: 80% aim to get rich, 50% want fame.
- Societal advice: Work hard, achieve more.
- Rare long-term life studies capturing choices & outcomes.

Objective: Track 724 men for 75 years, covering work, home life, health.
Challenges: Many similar studies fail due to dropouts, funding, or researcher changes.
Survival: Ongoing due to persistence and luck.
- Current status: ~60 original participants alive, 2000+ children now studied.

Two original groups:
1. Harvard sophomores (1938).
2. Boys from Boston’s poorest neighborhoods.
Methods:
- Interviews, medical records, home visits, etc.
Diversity in outcomes: Participants became professionals, some faced alcoholism or schizophrenia, social mobility.

Importance of Social Connections
- Socially connected people are happier, healthier, live longer.
- Loneliness is toxic: Lower happiness, early health decline, shorter lifespan.
- Study participation note: Harvard men vs inner-city men differences.
Quality of Relationships Matters
- Conflict impacts health negatively.
- Good relationships are protective, e.g., happier and healthier at age 80 if satisfied at age 50.
- Emotional impact: Good relationships mitigate physical and emotional pain in old age.
Relationship Quality & Brain Health
- Secure relationships in old age protect memory.
- Secure attachment moderates memory decline.
- Bickering less detrimental if relationship trust remains.

Good relationships: Essential but not a quick fix.
Lifelong effort: Importance of actively maintaining relationships.
Retirement happiness: Correlation with replacing workmates with new social connections.

Examples of "leaning into" relationships:
- Replace screen time with people time.
- Refresh relationships with activities like walks or date nights.
- Reconnect with estranged family.
