If you grew up in suburban Australia, you would be familiar with the green and gold trailers regularly appearing on our streets to mow our lawns. Jim’s Mowing has since expanded and the Jim’s Group is now the largest franchise in Australia and New Zealand with some 4,000 franchise owners turning over more than $500m a year serving 35,000 customers a day!

But don’t let the blue-collar grass mowing success story fool you – Dr David Jim Penman, that’s right…Dr, is an avid student of history and how its cyclical nature is determined by biology, epigenetics and character amongst other things.

Buckle up for a wild ride as we explore a huge range of topics including how civilisations are built, how to reverse their decline with epigenetics, why he is fighting the Victorian lockdown laws, and how Jim’s franchises are truly a family.
