Troian Bellisario—The Portal

Sasha Sagan talks to actor TROIAN BELLISARIO (Pretty Little Liars, Life on Mars) about a tradition older than our species, and the unusual (and slightly terrifying) way Troian once experienced it.

We'll also hear from professor and author RANDI HUTTER EPSTEIN (Get Me Out: A History of Childbirth from the Garden of Eden to the Sperm Bank) about the often strange and disturbing history of the tradition.
