Robert Sapolsky - #44: Youthful Appeal, Beauty & Goodness, Cerebellum | Robert Sapolsky Father-Offspring Interviews
The episode addresses why humans often want to appear younger, suggesting it's linked to fertility and health signals. This desire varies across cultures, with Western societies emphasizing youthfulness as a sign of fertility and attractiveness.
