Podbit · 2 Bears, 1 Cave with Tom Segura & Bert Kreischer
Tom Segura is doing a full gut-health investigation that requires him to defecate into a bucket, scoop samples into separate vials at three different temperatures, and deliver them to a lab. His goal: figure out why he can eat chicken and rice and have a wild shit, then eat a cheeseburger and be totally fine.

With mushrooms on their way via a mutual friend, Bert clarifies he's not doing a child's dose — he wants a hero dose, though he'll ease in with double a microdose first. What he really needs, he insists, is a shaman. Tom immediately says yes to recording a full podcast episode with both of them eating mushrooms guided by an actual shaman in Los Angeles, and adds he also wants DMT on the menu. Bert refuses the DMT add-on. The conversation shifts to Tom's gut health investigation, [1] — Tom Segura "Tom Segura is doing a full gut-health investigation that requires him to defecate into a bucket, scoop samples into separate vials at three…" 48:24 which may be the most unusual health story this podcast has ever produced: he must defecate into a bucket, scoop samples into separate vials maintained at room temperature, refrigerated, and frozen, then deliver them to a lab. His doctor specifically asked for a 'bad one.' The goal is to explain why his bowels are completely unpredictable — great food producing terrible results and vice versa. He and Bert compare daily bowel schedules in sincere detail, including Tom's trick of eating a jalapeño as a tracker to measure gastric transit time.
Bert is planning his first mushroom trip with a 'hero dose' and tells Tom he needs a shaman. Tom immediately agrees to do a full Two Bears, One Cave episode where both of them eat mushrooms guided by an actual shaman. Tom adds he also wants to do DMT. Bert says absolutely not.
Tom Segura is having his stool tested at a lab to determine why his bowel movements are so unpredictable, requiring him to scoop samples into vials and refrigerate or freeze them.
Bert Kreischer unknowingly defecated in his sleep, worked out afterward, and only discovered the incident the next morning in the shower.
Bert Kreischer accidentally defecated in his sleep, thought it was a fart, woke up, went to the gym, worked out, came home, and only discovered the evidence during his post-workout shower. His wife walked in and said 'it smells like balls in here.' He told her it wasn't balls.
AI nailed Andrew Huberman's vertigo-vs-low-blood-pressure diagnosis because that pattern has been reported millions of times. But every patient's liver is different and data on liver surgeries is scarce worldwide — making solo robot surgery dangerous. The rule is simple: data abundance means AI can help; data scarcity means keep the human in the loop.
Fei-Fei Li's father had liver surgery performed by a da Vinci robot guided by a surgeon. The result: 10 times less blood loss than a typical procedure. This isn't replacement — it's the gold standard of human-machine collaboration, where the human's judgment and the robot's precision combine.
US drug overdose deaths fell from 110,000 to roughly 70,000 — the biggest CDC-recorded single-year drop ever. Men's rates fell 27% in one year, and the steepest decline of all was among 15–24-year-olds, down 37%. The crisis narrative around young men needs to make room for signs of genuine progress.
Kessler thought his grief expertise would protect him. It didn't. When his son David died unexpectedly, he found himself on the floor — and eventually realized that acceptance alone wasn't enough. That unmet need became the sixth stage: finding meaning.
Grief isn't just death — it's any unwanted change. Kessler lectured at Coca-Cola and General Mills not because they had lots of funerals, but because change management is grief management. People who grieve well live well.
Witnessing someone's grief isn't just emotional support — it's an essential act of healing. Kessler argues grief is a severance and connection heals it. But real witnessing has two steps: seeing the pain AND affirming the person's capacity to recover.
Avoiding grief isn't free — it's exhausting. Kessler's beach ball metaphor nails it: pushing a small balloon down is easy, but holding a massive beach ball underwater takes constant, draining energy. Unattended feelings don't disappear; they just consume you.
Most people try to control their environment to avoid triggers. Kessler flips this entirely: triggers aren't problems to manage around — they're a detailed map to your pain and your healing. Every trigger points directly to what needs attention.
Running from pain doesn't leave it behind — it accelerates the chase. Whatever we run from pursues us, and whatever we face transforms us. Both Kessler and Lewis Howes testify to knowing both roads firsthand.
