The Truth About Longevity with Dr. Eric Topol

1 hour 2 minutes

What’s the secret to living longer and better? (Spoiler: It’s not a cold plunge or protein popcorn.) In this episode, we sit down with the brilliant Dr. Eric Topol — cardiologist, scientist, and author of Super Agers — to separate fact from fiction in the world of longevity.

We learn that blood tests are getting really good, GLP-1 drugs show real promise, and to always call Dr. Topol before you buy something TikTok tells you to. We cover everything from protein myths, weighted vests, and saunas to tests that could one day prevent Alzheimer’s and cancer. Penn and I also cover sleep tips, landlines, and Max Headroom. (Gen Xers, you get it.)

We hope this episode leaves you smarter, calmer, and surprisingly optimistic about the future of aging. We love to hear from you, leave us a message at 323-364-3929 or write the show at [email protected]. You can also watch our podcast on YouTube.
