Hardiness with Dr Paul Taylor

This podcast explores practical ways to protect your heart and support healthy aging. Dr. Paul Taylor talks with preventive cardiologist Dr. Ross Walker about the everyday habits that shape cardiovascular health, how to make sense of cholesterol and other risk markers, and where tests, medication, and supplements can help. Together, they cut through common health claims and discuss exercise, stress, diet, and emerging approaches to preventing heart disease.
The conversation focuses on practical prevention rather than late-stage treatment, with an emphasis on how much heart disease risk can be reduced before medication is considered. Ross explains what he thinks about cholesterol, coronary calcium scoring, statins, LP(a), MTHFR, and the future of cardiovascular medicine. It’s a wide-ranging, practical discussion for anyone interested in health span, not just lifespan.
Key topics
Dr. Ross Walker shares his background as a cardiologist of 47 years who shifted into prevention about 30 years ago after seeing repeated cardiac surgeries without lifestyle change.
The pair discuss his 80/10/10 model: 80 percent lifestyle, 10 percent orthodox medicine, and 10 percent evidence-based supplements.
Dr. Ross Walker outlines his five keys to health:
No addictions
Good-quality sleep
Simple nutrition
Regular exercise
Happiness and relationships
Five categories of stress
Emotional stress
Mental stress
Physical stress
Pharmacologic stress
Infective stress
Metabolic syndrome markers
High triglycerides
Low HDL
High blood pressure
Belly fat
Insulin resistance or diabetes tendency

Exercise is presented as one of the strongest interventions for heart disease, dementia, diabetes, depression, osteoporosis, and healthy aging.

This conversation explores how early life stress shapes the brain, why complex trauma is different from a single traumatic event, and how people can build resilience over time. Dr Paul Taylor speaks with Dr Eamonn McCarthy about forensic psychology, trauma work, performance psychology, and the practical ways therapy, exercise, sleep, and mindset can support change.
Stress can break you—or build you into someone stronger than you thought possible. Dr Eamonn McCarthy reveals why some people unravel under pressure while others turn hardship into resilience, and how trauma, recovery, and reappraisal shape that outcome. Paul and Eamonn trace the full stress continuum, from early life adversity and complex trauma to elite performance psychology. They unpack why uncertainty is so corrosive, how hyper arousal and hypo arousal show up in real life, and why the brain’s survival strategies can be both brilliant and heartbreaking.
They also discuss Larita Academy, a program helping disadvantaged young people unlock their potential, and Mind Your Monkey, which applies resilience and performance principles to executives and high performers.
You’ll discover:
Why adverse childhood experiences can rewire stress responses long into adulthood
The difference between hypervigilance, freeze responses, and emotional numbing
How reappraisal turns shame and trauma into post-traumatic growth
Why resilience is more like a muscle than a trait
How exercise, sleep, nutrition, and even creatine can support psychological change
Why trigger warnings and over-labelling mental health can backfire for some people
