The way we live now wasn’t designed for a 100-year life span. But that’s set to become the norm for children born today, and the well-established pathway of education-work-retirement is starting to crumble. Broadcaster and author, Jenni Murray, is joined by economist Andrew J Scott and social entrepreneur Katie Waldegrave to discuss why our modern lives need a redesign — and why a longer life span means we're more suited to a second career than ever before.

Now I'm Grown Up is hosted by Jenni Murray, produced by Antonia Cundy and Theodora Louloudis, and brought to you by Now Teach. The credits for this episode were read by Tye Hulbert.
