THE Identity Crisis
TW: This episode discusses depression, disordered eating, and substance use in the context of retired athletes. Take care of yourself, and reach out for support if you need it.
Izzy and Mia go back in time to unpack the identity crisis that hits almost every athlete after their sport ends: the withdrawal, the depression, the "who am I now" spiral nobody talks about. Mia brings the peer-reviewed data. This one gets personal, informative, and ends with our classic chaos. ENJOY.

A note on the research: the genetics/epigenetics studies show correlation, not causation, and the training-intensity study isn't a controlled experiment. The collagen debate hinges on how Myung & Park grouped trials by industry funding, which GROW (Gelatin Manufacturers of the World) and Collagen Stewardship Alliance dispute. We're sharing what the data shows, not overstating it.
