When an astrologer tells Mangesh that he’ll (probably) die early, he takes it in stride. But his family and friends (not to mention all the Don’t Die longevity influencers on his FYP) feel differently… and besides, if science can keep his brain sharp and his tennis game strong for longer, why not take advantage? So he visits Dr. Nir Barzelai, the world’s leading aging researcher, and Dr. Ron Primas, an elite longevity doctor, to figure out what he should do. Plus: A chat with Ken Reid from TV Guidance Counselor about age in pop culture, from the Golden Girls to “I’ve fallen and I can’t get up.”

Disclosure: The experts we spoke with want to be clear that although they have some minor quibbles with Bryan Johnson, they’re grateful for the fact that he’s started the conversation on longevity. Any insinuation that he’s got weird vibes is ours.

Here’s a recent favorite of ours from our friends at the Uncanny Valley podcast.

Actor Ben McKenzie (The O.C.) is out with a new documentary, Everyone Is Lying to You for Money, which follows his journey into becoming an anti-cryptocurrency advocate. He says we should all stop trying to unmask the presumed original developer(s) of bitcoin known as Satoshi Nakamoto because it benefits only the mysterious inventor. The actor-director talks with Katie about why he thinks crypto is a scam, and why he says people are falling for it.

Your brain is the last place companies don’t have access to… yet. But that’s changing fast. Nita Farahany, professor of law and philosophy at Duke University and author of The Battle for Your Brain, explains why the sci-fi future of mind-reading technology is here, and already sitting on the shelves at Best Buy. Dexter talks to Nita about how AI is learning to decode your mental state, how employers are using neurotechnology to monitor workers, and why this might be our last chance to protect the one thing that’s still private: what’s actually going on inside your head.

And be sure to listen through the end of the episode for a note from Dexter.
