I felt super ripped last night at a hot spring in South America. Pretty much the only male north of 30 without a belly and visible veiny muscles. I really forget I live in a bubble most of the time.

If you showed this to me 10 years ago I would congratulate you on a really cool SF video. This is real life where you have drones and tanks.
Many of you will have known for a while that if your plan is to defend with a load of cheap FPVs then upgraded tanks deployed as part of a package are going to chew through your position.

First day of a deload week. Super important for those of who are older (50yo), sometimes it good to take the foot off the gas for a week (or even have a vacation). You actually generally come back stronger most of the times.

Yesterday marked a unique day in my adult life.... I bought pants that had the same number on either side of the "x." 32x32. It was from @UniqloUSA which is not known for vanity sizing.... (yes, I bought the shirt there too). Pretty good look for a 50yo.

Happy Monday to everyone. I showered. But apparently it wasn’t good enough for the inspector here who decided I missed a few spots.

Hah. The other one was how strong my bones are. Which is another flex but not the one I was aiming for.

This makes me happy. Note he isn’t even focused like other on war fighting but on recovery.
This is truly a great man. He has invested more in Ukraine than 185 countries combined. Meet Howard Buffett, Warren Buffett’s middle son. He is 71 years old. He dropped out of college three times. He drinks Dr Pepper and looks for a McDonald’s wherever he travels. Since the beginning of the war, his foundation has become the largest private donor to Ukraine: $1.4 billion. Over four years, he has personally visited Ukraine 27 times. In April 2022, he saw burned-out agricultural machinery and called the president of John Deere: “How many combines are available in Europe?” “Fifteen. All of them were supposed to go to Russia.” “I’ll take them all.” Then came all the available New Holland equipment in Europe. Altogether, more than 100 tractors and combines were provided to Ukrainian farmers. He even tested demining equipment himself - on his own farm in Illinois, detonating explosives beneath rollers. When a Ukrainian deputy minister expressed doubts, Buffett told him: “Stop counting my tractors. If necessary, I’ll blow up a thousand of them.” Andriy Stavnitser initially asked him for $1 million for Superhumans. Buffett asked how much was needed to build the entire center. “$14 million.” “Okay. And what do you expect in return?” “Nothing. Build it.” Today, his support for Superhumans has reached $77 million, and the center has treated more than 1,700 patients. But his largest area of spending is neither agricultural machinery nor prosthetics. It is food: 642 million meals. And that is only part of it: * 344,000 windows replaced after Russian attacks; * 9 bridges, 4 power plants, 2,500 generators, and 18 DNA laboratories; * Much of Bucha rebuilt with his funding. “I already have more friends in Ukraine than I do at home,” he says. He celebrates birthdays in Ukraine, comes for Christmas, and even has a Ukrainian godson. Friends, this is truly a great man - someone who understands that he cannot take all his money with him when he leaves this world. I simply want to thank him and wish him well. Whatever else one may say, this is real help from a person who had no personal obligation to Ukraine. He simply chose to help. Source: translated from the original text by Oleh Bairak.

And this is why, when I see Moscow in flames, my heart cries “More.”
She was lying there, raped, her neck broken, with a noose around her neck. Beside her hung her 3-year-old son. When they took him down from the rope, he was blue and no longer breathing. But then a miracle happened. And what this child said a year later will break your heart. June 20, 2022. Kherson region, an occupied village. At two in the morning, the wife of a Ukrainian serviceman managed to message her husband that someone was breaking down the door to their home. His sister arrived an hour later. The gate was locked, so she climbed over the fence. The door had been ripped from its frame, and a window was smashed. Nothing had been stolen. They had not come to rob them. They had come to kill. In the room, her sister-in-law was lying on the couch, undressed and brutally beaten. Her head was twisted unnaturally, her neck was broken, and there was a noose around her neck. She was 28. Beside her hung her three-year-old son. He had also been beaten, with about a dozen cigarette burns on his face. The rope was pulled so tightly around his neck that the woman tore her fingernails bloody trying to untie it. The child was blue. His head was swollen from edema. He was no longer breathing. The woman screamed at him: “Breathe! Live! Because I won’t be able to live with this — I’ll lie down beside you and die too.” She performed CPR on him. She was afraid she would break his ribs — she didn’t. And he began to breathe. He had watched his mother being killed. And she had watched her child being tortured. The window had been broken — people nearby had heard what was happening, but no one admitted it. Then came three weeks in occupied Kherson. The woman waited for the burns and the rope mark around the child’s neck to heal. What had not healed, she covered with makeup so they would not be recognized and killed immediately. At the hospital, they warned her: “If they try to detain you, run. Half the hospital is occupied by FSB officers.” To get the boy out, the woman forged documents directly on her phone using Photoshop. She was taking him out as if he were her own son. Thirty checkpoints lay ahead. At one of them, a rifle was pressed against her temple. One Russian said, “Get rid of these two.” Another replied, “No, I’ve had enough for today.” The first said, “I’m fine with it.” He was wearing a wedding ring. Perhaps a wife and children were waiting for him at home. And he was perfectly fine with killing a woman and a child sitting in a car. Three days on the road. The woman pressed the pedals with one leg because the other had become paralyzed. At a filtration checkpoint, a young officer asked whether anyone in the car had survived torture. She said: “Yes.” Is anyone injured? — Yes. Has anyone been tortured? — Yes. When she pointed to the three-year-old child, the officer began to cry. He could not continue the conversation. In Odesa, doctors diagnosed the boy with clinical death, asphyxia, cerebral edema, a damaged wrist joint, a jaw injury, and eight broken teeth. He stopped speaking — his muscles had atrophied. His speech development was set back by a year. They now live in Odesa. The boy speaks again, goes swimming, attends kindergarten, and works with a speech therapist. He knows that his mother is gone. A year after the tragedy, he went outside one evening, pointed his little finger toward the sky, and said: “Moon, sky, Mommy.” The boy’s father is a serviceman. When they arrived in Odesa, he met them deeply devastated. He was able to stay with them for two weeks — as long as his command allowed. “He could have left the military and become his son’s guardian. But he didn’t. Because he is a patriot. Because he continues to fight,” she said. And after the liberation of the left bank of the Kherson region, there will be many more. Source: translated from the original text by Oleh Bairak.

Pushed myself hard with an upper body workout last night. 30,110 lbs moved in 41 minutes. Along with 14k steps. Went on a HIIT workout with my son this morning! (because you have to balance lifting with cardio)

Ukraine's fully justified response to Russia bombing the hell out them for the past 4 years seems to have been a bugle call to the sleeper cells/bots out there, as well as a bunch of low information people on the right. (and I say that with embarrassment as a conservative Rep)
Good morning and happy Moscow burning day 🔥

Don’t get hurt. Don’t get fat. Move. Pretty much my entire fitness philosophy in 7-9 words.

Eat lots of fiber (30-40g) and protein (180ish grams).

This is killer line. And yet getting a CAC scan requires effort and pushing for it. Heart disease kills ~800,000 Americans a year. Breast cancer kills ~40,000. We do 40 million mammograms and about 1 million calcium scans.
I'm a cardiologist. Dave Goldberg passed a treadmill EKG. Five months later he was dead at 47. His cholesterol wasn't scary. His stress test looked fine. His arteries were already full of plaque nobody had looked at. That's the story behind the CT trailer @altcap parked at the All-In Summit this week, scanning attendees and calling a $100 calcium scan "the mammogram for the heart." Why this is going viral right now: Because it's the perfect storm. A billionaire investor, not a doctor, parked a Siemens CT scanner in a truck at a tech conference and ran ~33 people through it in a day. A tragic story everyone remembers (Sheryl Sandberg's husband, the book Option B). A number anyone can understand (a score of 0 vs 400). A price anyone can afford ($100). And a villain: the cholesterol test your doctor keeps ordering that "missed it." Then the replies filled with people saying "I got a score of 600, they found two blocked arteries, I never had a symptom." Nothing spreads faster than a survivor story with a number attached. Plus a business model that sounds like a movement: employers pay $200, the extra $100 funds a free scan for someone in a low-income neighborhood. Medicare coverage is the stated goal, maybe by end of this year. Here's what he's right about, and where I'd slow him down. Heart disease kills ~800,000 Americans a year. Breast cancer kills ~40,000. We do 40 million mammograms and about 1 million calcium scans. That ratio is insane. Half of heart attack patients have "normal" cholesterol. Cholesterol tells you the risk of building plaque. A calcium scan tells you if the plaque is already there. The scan is 10 minutes, no needle, no dye. About 1 mSv of radiation. A mammogram is 0.4. You absorb ~3 a year just living on Earth. One scan is nothing. Scanning everyone every few years for decades is a different conversation. Score of zero? Your near-term risk is genuinely low. Score of 400? Something is happening in your arteries whether you feel it or not. In the uncertain middle, a high score vs a zero can mean a 7-fold difference in 10-year risk. In my own practice, I've seen a calcium score change more lives than almost any lab result. People who "felt great" and were walking around with a time bomb. Where I'd slow him down: The guidelines don't say "scan America." They say use it in adults 40 to 75 with borderline-to-intermediate risk, when the result would change whether you start a statin. The USPSTF still calls the evidence for population screening insufficient. A 2026 Northwestern study in JAMA found it adds only modestly to a good risk calculator for most people. Calcium is the scar, not the fire. Soft plaque, the kind that actually ruptures, doesn't show up. A zero in a 38-year-old is not a hall pass. Statins can make your score go UP as plaque hardens and stabilizes. So you can't use repeat scans as a "is my treatment working" meter. I have to explain this to scared patients every week. A high score can trigger the cascade: stress test, CT angiogram, cath, stents. In someone with no symptoms, stents often don't beat medication and lifestyle on hard outcomes. They add bleeding risk, a year of blood thinners, and complications. Incidental lung nodules show up. Anxiety shows up. Bills show up. And there's still no trial showing that scanning everyone saves lives. The "50,000 lives, $20 billion" math is a projection built on mammogram-scale volume, not a result. My honest take after 25 years: If you're 40 to 75, have family history, high Lp(a), South Asian or Middle Eastern ancestry, or your doctor is on the fence about a statin, this is one of the highest-ROI $100 in medicine. Get it. The scan is a flashlight. It's not the cure. The cure is still what it always was: apoB down, blood pressure down, sleep, movement, no cigarettes. Don't die of something preventable. And don't let a good test become a bad national product before the evidence exists. Get the data. Then argue with your cardiologist...

Anyone other than me given @ChatGPT a name? All the other ones don't feel awkward in voice mode (Claude? Grok? Even Gemini...). So yeah, now I call it Grace (I am Computer Scientist and live in Arlington VA, which has a park and now a school named after Grace Hopper).

The United States Navy has a warship whose bow was made from the World Trade Center. The men who built her lost their own homes in the middle of building her. They did not stop. In 2003, twenty-four tons of steel pulled from the wreckage of the Twin Towers were trucked south, out of New York, to a small foundry in Amite, Louisiana. Population about 4,000. The steel was to be melted down and poured into the bow stem of a new amphibious warship. The Navy had already chosen the name. USS New York. The men at the Amite foundry were metalworkers. They had melted steel their entire lives. Scrap is scrap. It goes in the furnace. This did not go in the furnace like scrap. Witnesses said the workers handled it the way people handle relics. Some of them reached out and touched it as they walked past, gently, the way you would touch a coffin. Nobody told them to. Nobody could have explained to an outsider why grown men in a foundry in rural Louisiana were laying their hands on twisted beams from a building fifteen hundred miles away. One man who had worked at that foundry for forty years was scheduled to retire before the pour. He postponed his retirement so he could be there when the towers went into the fire. On September 9, 2003, they poured. Seven and a half tons of World Trade Center steel became the stem of the bow. The leading edge. The part of the ship that touches the ocean first. The ship was built at the Avondale shipyard in New Orleans. Keel laid in August 2004. Twelve hundred Louisiana workers. Welders, pipefitters, electricians, shipwrights. Then, in August 2005, Hurricane Katrina came up out of the Gulf and drowned the city they lived in. Their houses were under water. Their neighborhoods were gone. Some of them lost family. The shipyard itself was hit. There was every reason on earth for the work to stop. The twelve hundred came back. Men who were sleeping in shelters, in trailers, in cars, showed up at the yard and went back to work on New York's ship. A firefighter from New York who came down for the christening said it out loud, the thing everyone in the yard already knew. This ship shows the strength of the country, past 9/11, past Katrina. Two cities, two disasters, one hull. She was christened on March 1, 2008, at Avondale, with the families of 9/11 victims in the stands. In the fall of 2009 she sailed for the first time, down the Mississippi and out into the Gulf and up the East Coast. On November 2, 2009, she came up the Hudson River into New York Harbor. She stopped in front of Ground Zero. The crew manned the rails in dress uniform. The ship rendered honors, a 21-gun salute, to the empty sky where the towers had stood, from a bow made out of them. Five days later, on November 7, she was commissioned into the Navy in New York, in front of thousands. Her crest shows a phoenix rising out of two gray towers. Her motto is on the crest. "Strength forged through sacrifice. Never forget." She is 684 feet long. She carries 800 Marines. She has deployed all over the world since. And at the very front of her, below the waterline, cutting through every wave she has ever met, is seven and a half tons of the World Trade Center. The steel that fell on September 11 was twisted, black, and buried. Louisiana dug it out, melted it, and sent it back to sea. Pointed forward. Hitting the waves first. 🇺🇸

25 years ago. I remember seeing the smoke from the Pentagon (and later smelling the smoke that still lingered in NYC), worrying about my family members that worked in DC and NYC. I joined the Government, then the Army National Guard, deployed to Afghanistan. 9/11 changed my life
