#346 First Principles — Henry Totterdell
What happens when a mechanical engineer spends a decade fixing factories, then walks away from it all to start dental school at 34? Henry Totterdell joins Payman to tell that story. He talks about the years spent solving problems on aircraft carriers and chemotherapy production lines, the slow-burning itch to do something with his hands, and why he finally took the plunge. Along the way they get into first principles, the magic of human connection over Zoom, where robots might fit into the chair one day, and the quiet privilege of a patient simply saying thank you. It's a conversation about taking the long way round — and arriving exactly where you meant to.In This Episode00:01:55 - Travel and adventure 00:05:20 - Childhood in Stroud 00:06:15 - Choosing engineering 00:07:35 - Loughborough years 00:08:45 - Engineering versus dentistry 00:10:00 - First principles thinking 00:12:10 - Life as a consultant 00:17:15 - Losing his purpose 00:18:35 - The pharmaceutical world 00:21:00 - The itch to do medicine 00:22:15 - Working with his hands 00:23:50 - The leap to dental school 00:31:50 - The Innovations Hub 00:36:05 - First extraction 00:38:40 - Blackbox thinking 00:43:45 - Starting a business 00:44:55 - Lectures that stuck 00:48:10 - What makes a course brilliant 00:50:25 - The magic of being in the room 00:52:15 - Soft skills and integrity 00:54:20 - Reading the patient 00:57:45 - Regrets 01:01:45 - Robots in the chair 01:06:00 - Relentless optimism 01:06:45 - Darkest days 01:10:20 - Nervous patients 01:13:40 - Awards and recognition 01:16:20 - Confidence and family 01:18:35 - Fantasy dinner party 01:20:45 - Last days and legacyAbout Henry TotterdellHenry Totterdell is a third-year dental student at Bristol, having come to dentistry after a decade as a mechanical engineer and consultant. A Loughborough graduate, he worked across defence, pharmaceuticals and manufacturing before retraining at 34. Alongside his studies he runs a Dental Innovations Hub at Bristol, introducing students to the technology and business side of dentistry that the course doesn't cover.
