Can you tell someone's testosterone or estrogen levels just by looking at their face? Is "jawmaxxing" actually backed by science? In this video, we dive deep into the real science of hormones, physical attraction, and evolutionary biology.

We debunk popular myths around high testosterone, facial masculinity, and ovulation preferences, revealing what the research actually shows about human mate selection. Discover why facial structure isn't a hormone panel, how estrogen impacts skin and collagen as women age, and why physical strength accounts for 70% of perceived bodily attractiveness.

If you want to understand how hormones shape our development—and why muscle is the single most modifiable signal of health and longevity—this episode is for you.
