Podcast: How to Be a Better Human
Episode: How to strengthen your relationships — one airport ride at a time (w/ Kasley Killam)
Host: Chris Duffy (TED)
Date: October 6, 2025

In this eye-opening episode, host Chris Duffy sits down with Kasley Killam, author of The Art and Science of Connection, to discuss why social health is as vital as physical or mental health—and how, in a world that values independence and frictionless convenience, we might be robbing ourselves (and others) of genuine, life-changing human connection. The conversation explores the science backing the health benefits of meaningful relationships, practical strategies for building your “social fitness,” and the psychological barriers many of us face when reaching out. With warmth, vulnerability, and practical wisdom, Killam and Duffy urge listeners to take small, sometimes uncomfortable steps—like asking for help or a ride to the airport—that can enrich and transform their lives.

Key Discussion Points & Insights

The Crisis of Disconnection

• Modern Loneliness is a Public Health Crisis
  • Killam highlights troubling statistics:
    • One in four people globally feels lonely, and 20% of adults have no one to reach out to for support.
    • Loneliness is linked to higher rates of disease, depression, dementia, and premature death.
      Notable quote:

    “One in five people you encounter may feel like they have no one. This is more than heartbreaking, it's also a public health crisis.” – Kasley Killam [01:16]

Social Health Defined

• Social health is distinct yet as vital as physical or mental health.
  • Defined as having meaningful relationships, regular interactions, and a sense of belonging.

    “Decades of research at this point have shown that human connection is so much more important than we realize. ... Our relationships are actually determining how long we live.” – Kasley Killam [04:55]

  • Maintaining meaningful relationships should be seen as essential for health—comparable to not smoking, eating well, or exercising.

    “If you had a really healthy level of connection ... that is more important for your health than anything short of smoking cigarettes.” – Chris Duffy [05:50]

The 5-3-1 Rule: A Practical Framework

• Guideline for Social Health:
  • Aim to connect with five different people each week
  • Cultivate at least three close relationships
  • Spend one hour per day connecting (can be in small increments)
  • Quality is more important than quantity, especially for introverts.

    “If you want some sort of number ... five different people each week, three close relationships, one hour a day connecting.” – Kasley Killam [06:51]

• Diversity of Interactions Matters:
  • It’s uniquely beneficial to connect with people from varying backgrounds and roles (not just close friends/family).

    “Engaging with people who come from a different background ... that's actually uniquely beneficial.” – Kasley Killam [11:12]

The Quality vs. Quantity Debate

• Balance Your Energy & Needs:
  • For extroverts, higher numbers of interactions may feel energizing, while introverts benefit from fewer, deeper connections and need time to recharge. [07:58]
  • The key is understanding and respecting your personality while “stretching your social muscles.”

Small Changes with “Big Bang” Social Impact

• Low-barrier ways to connect:
  • Regular, scheduled interactions (like a weekly breakfast) remove “activation energy.”
  • 10-minute phone calls with loved ones a few times per week measurably reduce loneliness. [13:12]
  • Brief touchpoints (“thinking of you” texts, sharing a memory, etc.) matter.

    “Little touch points like that can be really meaningful.” – Kasley Killam [13:12]

• Social maintenance is like physical exercise:
  • People block off time to go to the gym, but often let time with friends slide to the bottom of the priority list—even though it’s just as vital for long-term health.

    “We easily let our relationships come last.” – Kasley Killam [15:18] “Connection is essential. It's actually determining how long we live.” – Kasley Killam [15:18]

The Downside of Frictionless Convenience

• Efficiency Culture vs. Connection:
  • Modern technology (rideshare apps, grocery delivery, etc.) often removes opportunities for spontaneous human interaction—and the “friction” that forges bonds.

    “By designing everything to be as easy as possible ... we're removing the magic of spontaneous connection.” – Kasley Killam [21:01]

• The Airport Ride Metaphor:
  • Culturally, we often avoid asking friends for “burdensome” favors like a ride to the airport, but these are chances to strengthen relationships; helping makes people feel valued.

    “That's actually robbing people of the chance to help us. ... We deepen our connections when we help other people.” – Kasley Killam [21:49]

  • Both Chris and Kasley admit they struggle with asking for help, despite enjoying being asked for help by others. [22:22]

Why We Struggle to Ask for Help (and How to Overcome It)

• Limiting Beliefs Lead to Isolation:
  • Many people worry that asking for help is burdensome or makes them less likable—yet research shows people typically enjoy being asked and feel more connected as a result.

    “Our own limiting beliefs often get in the way of us being socially healthy.” – Kasley Killam [33:39] “People like us more than we think ... Most of the time, people want connection. And it feels so good when someone is like, hey, I miss you.” – Kasley Killam [34:01]

• Practical Challenge:
  • Kasley challenges Chris (and listeners) to experiment: once a week, ask someone for a favor or help—a small “friction” that feels uncomfortable—and notice the results.

    “Do it as an experiment ... Try one thing where you’re asking someone in your life to help you ... and then see how it goes.” – Kasley Killam [31:39]

  • Chris responds with honest vulnerability:

    “That feels scary. ... This one, I'm like, you're terrified.” – Chris Duffy [32:39]

Connection and Technology: Double-Edged Sword

• AI & Social Media Are No Replacement for Real Connection:
  • AI chatbots used as companions may increase loneliness rather than decrease it (recent MIT Media Lab and OpenAI study).

    “AI chatbots for companionship are not making us less lonely, they're making us more lonely.” – Kasley Killam [24:38]

• Tech Can Also Build Community—for the Isolated:
  • For marginalized or geographically isolated people, online groups can provide unique support networks (e.g., rare disease communities or LGBTQ+ groups). [39:12]

Social Connection Across Groups, Ages, and Genders

• Men’s Friendship Recession:
  • Data show a sharp decline in close friendships among men, with many relying solely on their partners for social connection.

    “There’s a men friendship kind of recession ... where men are relying on their wives in a lot of cases to be that source of social connection.” – Kasley Killam [37:23]

  • Solution: join group activities, sports teams, or hobby-based gatherings—group belonging is powerful even without close one-on-one bonds.
• Kids, Social Media, and the Messiness of Connection:
  • Social technologies can both help and hinder connection among youth; the risks often depend on context, norms, and group inclusion/exclusion.
