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.
