Patrick Samy is the co-founder and CEO of Span Health, a start-up that offers health coaching informed by biometric data from lab work and wearable devices. Like me, Patrick started out as a software engineer confronted with his own health challenges. Pairing his curiosity for biology with his background in computer science, and adding in a new generation of more accurate consumer health and fitness devices, Patrick is leading Span Health to enable everyday athletes to take their health and performance to a new level.

In this podcast, Patrick talks about the value of personal biometric data for finding your individual path to optimal performance and longevity. He shares lessons learned from his own experiments with wearable data trackers, and trends he's observed while working with clients. We also discuss his go-to devices and biomarkers to track, and the lifestyle interventions that make the biggest difference.
