Shownotes
This week I'm joined by Dr Jack Kreindler, physician, healthtech entrepreneur and founder of WellFounded Health and the Centre for Health and Human Performance, and someone who has spent 26 years asking one of the most important questions in medicine, what does it mean to not just fix disease, but to truly enhance human life?
We explore longevity, prevention, performance and what the most advanced medicine in the world is learning about how to live well for longer.
Dr Jack Kreindler qualified in medicine and physiology from University College London and spent a decade as an emergency physician before founding the Centre for Health and Human Performance in Harley Street in 2007. He is an honorary clinical research fellow at Imperial College London, founder and CEO of WellFounded Health and a leading voice on healthy longevity, human performance and the future of medicine. He has worked with elite athletes, extreme environment explorers and high performance executives across the world.
What we explore together:
• Why medicine is shifting from fixing disease to enhancing physiology and what that means for you
• What burning the candle at three ends is actually doing to your brain and body
• Why cadence is king and how everything in nature and biology moves in waves
• What the most advanced health testing actually looks like and what it tells us
• The truth about longevity supplements, peptides and biohacking and who they actually work for
• Why your history is still the most powerful diagnostic tool ever invented
• What it really means to enhance a human life rather than just extend it
Love, Sarah Ann 💛
