What We Can Still Learn from Gratton & Scott’s The 100‑Year Life

IMPACT: Monash Business School

In this episode of the IMPACT podcast, Dr Nga Pham speaks with economist and longevity expert Professor Andrew J. Scott, co‑author of The 100‑Year Life. Five years after the book’s release, they revisit its core message: that rising life expectancy is reshaping how we work, learn, save, and live. Scott explains why the traditional three‑stage model — education → work → retirement — is no longer fit for purpose, and how individuals, organisations, and governments must adapt to a world where most children born today are likely to live into their 90s. The conversation blends economics, demographics, and practical guidance for navigating a multi‑stage life.

Key Insights

  • Life expectancy continues to rise, making multi‑stage lives the new norm.
  • Traditional “learn‑work‑retire” structures no longer match real human behaviour.
  • Longer lives require new approaches to skills, savings, health, and time use.
  • Longevity is not “more old age” — it’s more time at every age, creating new possibilities.
  • Organisations must rethink career design, flexibility, and support across life stages
