United Hatzalah is a volunteer emergency network in Israel with 18,000 volunteers who handle 2,000 calls per day. Their goal is a 90-second response time, and they currently hit about 2–3 minutes — versus the standard 12-minute ambulance. It was built because a child choked and died while a nearby doctor had no idea.

Sam Parr sat down for dinner with Mark, who co-founded both the expert-network giant GLG and a very different kind of venture: United Hatzalah. The origin story is stark. A child was choking. An ambulance was called. The ambulance didn't arrive in time. The child died — even though a doctor lived nearby and had no idea anything was happening. That frustration drove a man named Eli to start a small network of trained volunteers who could be dispatched faster than any ambulance. He started with 6 to 12 people, trained in CPR, the Heimlich maneuver, and emergency delivery, each carrying a 40-pound supply backpack. Mark gave him $18,000 and became his co-founder. [1] — Sam Parr "United Hatzalah is a volunteer emergency network in Israel with 18,000 volunteers who handle 2,000 calls per day. Their goal is a 90-second…" 09:03 Eighteen years later, United Hatzalah has 18,000 volunteers across Israel, handles 2,000 calls a day — one every 45 seconds — and operates with an average response time of 2–3 minutes against a 12-minute ambulance benchmark. Their goal is 90 seconds. They use AI trained on 18 years of data (heart attacks peak in the morning; people are home, not at the office) to pre-position volunteers. The network is powered entirely by donations and spends tens of millions of dollars per year. It's also, Mark told Sam, one of the only places in Israel where ultra-Orthodox Jews, secular Jews, Arabs, Muslims, and Christians work side by side — not through dialogue, but through shared action.
Shaan Puri attempted to use the rule of reciprocity by bringing Diet Cokes to a tense meeting with a school principal, but the principal refused the drink and shut down his program anyway.
GLG (Gerson Lehrman Group), the expert network company, generates over $100 million a year in profit and cash flow based on public filings from when it attempted to go public.
United Hatzalah's mission is to reach any emergency in Israel within 90 seconds; they currently achieve an average response time of about 2–3 minutes, versus the standard 10–12 minutes for ambulances.
United Hatzalah, Israel's volunteer emergency network, handles approximately 2,000 calls a day with around 9,000 volunteers across the country.
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.
