Friendship is hard right now. Which is why today, Mel is sitting down with Harvard-trained social scientist and bestselling author, Kasley Killam, who has spent the last 15 years researching friendship, connection, and loneliness.

There's a reason for all of that. And today, Kasley is giving you the answer.

No matter your age or stage of life, it’s not too late.

If you’ve felt lonely, disconnected, or like building real friendship is impossible, this conversation will show you exactly what to do next, with steps that are simple, specific, and realistic.

Key takeaways

  1. You keep telling yourself you're too busy, but the truth is your life feels like a blur because you’ve stopped prioritizing connection, and without it your relationships fade, leaving you feeling lonely and disconnected.

  2. You say you’re tired and cancel plans, but what you don’t realize is that connection is the medicine, because being with people actually boosts your energy, builds resilience, and reduces the stress you’re trying to escape. 

  3. You think loneliness means something is wrong with you, but it’s actually a biological signal your brain sends, just like hunger, telling you that you need connection, and ignoring it only deepens isolation over time.

  4. You underestimate how much people like you, but research shows your self-doubt distorts reality, making you hold back when in truth others feel more warmth and appreciation toward you than you believe or expect.

  5. You don’t need more time, you need different choices, because even a quick text or call can create real connection, and when you choose scrolling instead, you’re trading meaningful relationships for empty distraction.

Kasley Killam, MPH

Kasley Killam, MPH is a Harvard-trained social scientist who has spent 15 years studying how human connection impacts your health, longevity, and happiness. She is a leading expert in social health and the author of The Art and Science of Connection.

  • The Art and Science of Connection: Why Social Health Is the Missing Key to Living Longer, Healthier, and Happier

    Exercise. Eat a balanced diet. Go to therapy. Most wellness advice is focused on achieving and maintaining good physical and mental health. But Harvard-trained social scientist and pioneering social health expert Kasley Killam reveals that this approach is missing a vital component: human connection.

    Relationships not only make us happier, but also are critical to our overall health and longevity. Research shows that people with a strong sense of belonging are 2.6 times more likely to report good or excellent health. Perhaps even more astonishingly, people who lack social support are up to 53% more likely to die from any cause. Yet social health has been overlooked and underappreciated—until now.

    Just as we exercise our physical muscles, we can strengthen our social muscles. Weaving together cutting-edge science, mindset shifts, and practical wisdom, Killam offers the first methodology for how to be socially healthy. An antidote to the loneliness epidemic and an inspiring manifesto for seeing wellbeing as not only physical and mental, but also social, The Art and Science of Connection is a handbook for thriving.

    In this essential book, you will:

    Learn a simple yet powerful framework to understand, evaluate, and bolster your social health.

    Discover the exact strategy or habit you need, as well as research-backed tips, to cultivate and sustain meaningful connection now and throughout your life.

    Glean actionable insights to develop a sense of community in your neighborhood, at work, and online from a spirited group of neighbors in Paris, the CEO of a major healthcare company, and an artificially intelligent chatbot.

    Get an insider look at the innovative ways that doctors, teachers, entrepreneurs, architects, government leaders, and everyday people are catalyzing a movement toward a more socially healthy society.

    The Art and Science of Connection will transform the way you think about each interaction with a friend, family member, coworker, or neighbor, and give you the tools you need to live a more connected and healthy life—whether you are an introvert or extrovert, if you feel stretched thin, and no matter your age or background. Along the way, Killam will reveal how a university student, a newlywed, a working professional, and a retired widow overcame challenges to thrive through connection—and how you
