Welcome back to The Long Game. I am Lucas Ferreira. Today we are talking about rapamycin, the drug that makes mice live longer and that a surprising number of healthy people are now taking every week, on their own initiative, because of what they read online. To help me I have Dr Ingrid Weber, a clinical pharmacologist who has spent her career on exactly this class of drugs. We will explain what rapamycin does inside a cell, why it works so well in mice, what the handful of human trials have actually found, and the side effects that do not make it into the posts. And I will tell you honestly whether I would take it myself. Ingrid, welcome to the show. You are listening on Witspeak Podcasts.
