Episode summary
What should I tell my future son about growing up in a world that clashes with our evolutionary wiring?
Teach him the mismatch idea: traits that helped our ancestors can turn harmful in modern abundance, like craving fat and sugar when food is everywhere, which fuels many leading diseases. Knowing this gives him an edge to spot and sidestep those built‑in traps.
Your book on happiness lays out a roadmap; what should I actually point him toward for a good life?
Two choices loom largest for joy or misery: your partner and your work, because waking up beside someone you deeply like and then spending the day on energizing projects is hard to beat. Life is probabilistic, so aim to raise the odds by choosing value alignment over the short‑lived buzz of opposites.
For nuance, my partner loves spiritual stuff like crystals, and I’m into soccer; we seem great together despite those differences.
It’s not about matching tastes; it’s about shared fundamentals like honesty and high personal standards, including never playing jealousy games, football banter aside. When those cores align, the rest is color, not conflict.
Are there qualities in your wife you lack but love because they stretch you?
She’s a MacGyver type who can build solutions from scraps, and I’m in awe of that hands‑on ingenuity. For all my theory, she’s the one who makes rockets out of spare parts, and I adore it.
What’s the evolutionary reason we crave meaning and purpose beyond happiness?
Because we’re conscious, survival and reproduction aren’t enough; we seek narratives and goals that lift life above instinct. Happiness is roughly half genetic, and work that grants time freedom and lets you create—like turning a blank page into a book—feeds purpose in a direct way.
You’ve written that youngest siblings skew creative; if creativity boosts happiness, are we laterborns actually happier, and by the way, most founders at my dinner table were the youngest.
Frank Sulloway’s Born to Rebel argues kids carve unique niches as families grow, pushing laterborns toward openness and rule‑breaking that fuels innovation. I found the same in consumer behavior with lastborns leading on new products, so if openness tracks with well‑being, laterborns may enjoy a happiness edge.
That fits my story: looser rules meant more experimenting, small hustles, and risk‑taking that built confidence; it’s probably a mix of freedom and attention‑seeking.
Likely both; my wife and I are each lastborns, and I’d love to see a simple study on whether couples assort by birth order and how that links to marital satisfaction.
