Key notes

What to take away.

  1. 01
    Following whole lives

    The study tracked the same men from their teenage years into old age, asking about their work, home life and health.

  2. 02
    Loneliness is toxic

    People more connected to family, friends and community were happier, healthier and lived longer.

  3. 03
    Quality beats quantity

    It's not how many friends you have, but how good your close relationships are.

  4. 04
    Relationships at 50 predict health at 80

    The people most satisfied in their relationships at 50 were the healthiest at 80.

  5. 05
    Good relationships protect the brain

    People who felt they could count on their partner kept sharper memories for longer.

  6. 06
    Lean in to relationships

    Swap screen time for people time, try something new together, or reach out to someone you haven't spoken to in years.
