Dr. Caroline Leaf Podcast

Pick My Brain is Dr. Caroline Leaf's new Q&A series — you send the questions, she answers them with real neuroscience. No fluff, no generic advice. Just honest answers to the things you're actually dealing with. This week's theme: why adult friendships are dying — and what's happening in your brain when they do. You have 500 followers and no one to call at 2 AM. The number of Americans with no close friends has quadrupled since 1990. The U.S. Surgeon General has declared loneliness a public health crisis — one that increases your risk of premature death by more than 60%. And yet no one talks about it honestly. In this episode, Dr. Leaf takes real listener questions on the loneliness epidemic: why friend breakups hurt worse than divorce, why your husband's silence might literally be killing him, what happens in your brain when a friendship turns toxic, and whether it's actually possible to make real friends after 40.
