What actually helps you look younger, feel better and improve how you age after 40? In this episode, I explain the Brain First approach I use to think about healthy aging, brain health and longevity—and why collecting supplements, peptides, wearables and other longevity interventions is not the same thing as having a strategy.
You’ll learn how sleep, movement, muscle, metabolic health, nutrition and inflammation interact as a system, why improving one area can influence several others, and how to identify where you should start instead of trying to optimize everything at once.
IN THIS VIDEO, YOU WILL LEARN:
✅ Why supplements, peptides, NAD+, cold plunges and other longevity tools are not an implementation strategy
✅ How sleep, movement, muscle, belly fat, insulin resistance and inflammation can interact as you age
✅ How the Brain First approach uses interconnected health factors to help you identify where to start and build a more personalized longevity strategy
