At 71 years old, RFK Jr. shrunk his visceral fat by 40% in a 30 days.
Most men his age are on blood pressure meds and statins.
Dr. Sean O'Mara helped him reverse atrial fibrillation with food alone.
Here's the protocol he followed (and how to copy it):🧵

1. Shift to a meat-and-ferments base.
RFK ate carnivore plus fermented foods the entire day.
Saturated fat and protein kill cravings.
Ferments like kimchi, sauerkraut and kefir fix the gut.

2. Cut off your insulin.
Visceral fat thrives on one thing: constant insulin spikes from snacking, seed oils, and refined carbs.
Drop them for 30 days and your liver starts dumping fat it's hoarded for years.
This shrinks visceral fat faster than any gym routine.

1/x I received a question about what the "Baltic Dry Index" is. First, I have to explain what the Baltic Exchange is. It is one of the world’s oldest and most respected institutions in global shipping and maritime trade.
2/x The story begins in 1744 at the Virginia and Baltick Coffee House on Threadneedle Street in the City of London, near the Royal Exchange. Merchants, shipowners, brokers, and charterers gathered there to exchange news, negotiate deals, and arrange the chartering of ships.
3/x Initially, the focus was on trade with Virginia, Maryland, and the Baltic region. After American Independence, the emphasis shifted to trade with Russia. London was becoming the world’s leading shipping and trading center.

At first I thought she was laughing at the aging infrasturcture in Haifa.
Nope. She thought that a manhole cover from the British Mandate somehow "debunks" Israel.
But the one she shared was manufactured at Vulcan Foundries, which was founded by a company called "Foundries and Metal Works of Israel Ltd." It was owned by Alexander Kremner, a Jew originally from Germany who made aliyah.
Kremner's name is written in Hebrew letters on the manhole cover. You can see it in the photo she shared, if you zoom in.
Being deeply confused about history isn't just a side effect of the Free Palestine movement. It's a membership requirement.

Germany just won 7-1.

Because what I saw was one of the most exciting attacking teams in world football…

Germany looked completely in control for long stretches.
But the structure behind it tells a more complicated story.

Six players committed high.

create constant central combinations
win games through movement, not structure

🚨 THREAD: What do Mike Pence, Mike Pompeo, John Bolton, and Elaine Chao have in common? They were all paid by a Marxist-Islamist Iran group that was designated as terrorist until 2012.
No, this is not a joke.
Mojahedin-e-Khalq (MEK) was founded by leftist Islamists to oppose the western-backed Pahlavi, and participated in his 1979 overthrow. Khomeini barred MEK afterwards. MEK was implicated in multiple bombings, including that of Americans, and remained an openly armed group until 2003.
Since they got de-listed as a terrorist organization in 2012 on procedural grounds, MEK and their fronts have been actively recruiting US politicians selling themselves as a moderate alternative to Khomeini. But RAND Corporation says MEK meets the qualifications for a cult, citing criteria such as forcing their members to work 16+ hour days and forced divorces.
Polls of the Iranian-American community shows that they do NOT accept Rajavi, MeK's leader, as legitimate, with a 46-point net disapproval - numbers nearly as bad as the existing regime.
As Pence's former Chief of Staff, Marc Short, has already weighed against Trump deal, it's helpful to recall this.

Fred Rogers met with a child psychologist every week for 22 years to build his show. She shaped everything: every script, prop, and song. The whole point was to give a child's nervous system time to slow down. In 1984, a single regulatory decision ended all of it.
The psychologist was Dr. Margaret McFarland, who co-founded the Arsenal Family and Children's Center alongside Benjamin Spock and Erik Erikson. She and Rogers understood that the prefrontal cortex in children, the part of the brain that controls impulse, emotion, and attention, takes decades to fully develop. At the start of every episode, Rogers tied his sneakers and changed his sweater while children settled in. Those pauses were intentional, designed to help a child's nervous system shift into a calmer, more focused state.
What ended it had nothing to do with child development science. In 1984, Reagan's FCC chairman Mark Fowler abolished the advertising limits that had protected children's programming from commercial pressure. Toy companies moved within months. Between 1984 and 1985, cartoons tied to toy lines increased by 300%, from a handful of shows to more than 40 animated series. In almost every case, the toy was designed first. The cartoon was built to sell it.
Researchers later put numbers to what parents were already noticing. A 2011 study in Pediatrics from the University of Virginia tested 60 four-year-olds across three groups: one watching SpongeBob, which cuts scene every 11 seconds; one watching a slow PBS show, which cuts scene every 34 seconds; and one drawing. Nine minutes later, all three took tests on attention, impulse control, short-term memory, and problem-solving. The SpongeBob group scored significantly worse across every measure.
In the 1970s, children began watching television around age 4. Research from pediatrician Dimitri Christakis found that by 2009, the average age of first screen exposure had dropped to 4 months, as the content got faster and the audience got younger. Researchers separately found that each additional hour of daily screen time at ages 1 or 3 raised the risk of attention problems at age 7 by 9%.

Part 2. Your child's brain cannot calm itself down. Not at 2, not even at 4. Until around age 6, the part of the brain that regulates emotion is too undeveloped to manage it alone. Children need to borrow a calm nervous system from the nearest adult.
There's a name for this: co-regulation. When a caregiver speaks steadily, moves slowly, or simply stays calm nearby, the child's nervous system starts to synchronize with theirs. Both heart rate and stress hormones adjust. The calm transfers through the body.
A slow, predictable screen can do something similar. When the pacing is unhurried and nothing unexpected happens, the child's parasympathetic nervous system, the branch responsible for slowing heart rate and promoting recovery, stays active. Rogers understood this long before most people designing for children began thinking about it. His quiet voice, his predictable routine, his transitions so slow they'd bore most adults: all of it was calibrating a child's nervous system at the same time it entertained them.
Fast content activates the opposite branch. Rapid cuts, sudden sounds, and unpredictable movement trigger the sympathetic nervous system, the body's stress and threat response system. The child's body prepares to react. The trouble is, that reaction doesn't stop when the screen does. The nervous system stays activated after the show ends, which is why children so often melt down right after watching high-stimulation content: the alarm turned on, and nothing turned it off.
A study from Texas Tech University, published in the Journal of Children and Media, found that preschoolers who watched Daniel Tiger's Neighborhood scored measurably higher on empathy and emotion recognition, but only in households where parents watched alongside them and talked through what was happening on screen. Left to watch alone, the children's scores didn't move.

1/ The dopamine reset most adults need.
Most adults who think they have ADHD do not have ADHD.
They have something else.
Andrew Huberman said it plainly. Heavy phone use floods the brain with too much input. Email. Texts. Three apps. Two real talks. Fifteen tabs. All at once.
Your brain stops being able to focus on one thing. You trained it to expect a new hit every six seconds.
Huberman calls it a form of ADHD. He said the brain can start to look just like a brain with real ADHD. The good news is that it can heal.

2/ A 2020 brain scan study proved this is not just a theory.
Scientists used a PET scan to study 22 healthy adults. None of them had ADHD.
They tracked each person's daily phone use for weeks.
The result was clear. The more time someone spent on social apps, the lower their dopamine levels were in a key part of the brain called the putamen.
The putamen is the same part of the brain that is broken in real ADHD.
