The Longevinauts: A Personal Investigation into Living Forever

Host Mongai Shit was 47 when he started noticing the cultural noise around longevity—billionaires injecting themselves with cow brains, biohackers tracking every erection, and influencers promising to reverse aging. He wasn't particularly interested in living forever. But then a tantric astrologer in Chennai told him he would die at 64, and his wife and friends reacted with something he hadn't expected: anger that he was so accepting of the timeline.

The Prediction That Changed Everything

The astrologer had been accurate before. Years earlier, he had predicted the exact time Mongai's father would die, and the prediction came true. During a re-listening of old interview tapes for a previous show, Mongai discovered a forgotten part of their conversation: the astrologer's prediction for his own life. "From 2034 of 10th month till 2039 after month you will read what you are," the astrologer said. "Then boom. End of this life." July 29, 2039 became a critical date—Mongai would be 64.

Show Notes

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.

Special thanks to Azadi Records and Bliss Samsa for their beautiful tracks, and Botany for the score.
