Dr. David O'Donnell is a ticker-ologist. He's specialises in tickers. The sciencey folk call him a cardiologist and electrophysiologist. Not surprisingly, we had a chat about what us potential patients can do to avoid becoming an actual patient, any time soon. And despite the fact that he's quite a skilled ticker-ologist, he'd rather not see you or me on his (or any) operating table. He's all about being proactive, not reactive and optimising our chances of a long health-span and lifespan by making smart decisions and doing smart things before the metaphoric wheels fall off the medical wagon. This was a revealing, educational and motivating chat (for me anyway) and I hope you enjoy it.
