Short YouTube conversation between Bárbara Tijerín and Oso Trava. Bárbara explains differences between authentic (Duchenne) and fake smiles, ties authentic smiles to the limbic emotional brain and eye-muscle activation, and discusses social patterns (employees smile more than bosses; women smile more than men) and risks of misinterpretation. Oso notes anxiety behaviors (fidgeting, arranging objects) as personal coping; Bárbara describes a distractor technique (holding a pen) used by a advisee. The clip includes a promotional call-to-action for the Endeavor Crack Summit (May 27–28) and ticket purchase link.
