The Optispan Podcast with Matt Kaeberlein
Optispan
Optispan is a vision for what health should be.
The typical person gives up 10-20 years of quality life in exchange for disability, frailty, and early death. We call this "the lost decade". Time that should be spent with loved ones doing the activities you enjoy are instead spent suffering from multiple diseases and taking a cabinet full of medications that probably do as much harm as good.
We believe that the current practice of medicine is disease care, not health care. We believe that everyone can get closer to their own optimal healthspan.

I spent the first few decades of my career doing scientific research into the biology of aging, trying to understand the finer details of how humans age in order to facilitate translational interventions that promote healthspan and improve quality of life. Now I want to take some of that knowledge out of the lab and into the hands of people who can really use it.On this podcast I talk about all things aging and healthspan, from supplements and nutrition to the latest discoveries in longevity research. My goal is to lift the veil on the geroscience and longevity world and help you apply what we know to your own personal health trajectory. I care about quality science and will always be honest about what I don't know. I hope you'll find these episodes helpful!
