I never would have guessed that one of @ostrohealth early failures would end up memorialized in @Entrepreneur. If you’d asked me in 2020, I would’ve assumed that story stayed buried in a notebook somewhere. But here we are... entrepreneur.com/building-a-bus…

@ValerieAnne1970 @ValerieAnne1970 - I urge you to stop spreading misinformation about LDL-C and statins. What is more concerning is the number of educated, high health literate individuals who are watching this and believing it to be true. This demonstrates a much larger health literacy issue.

🔥BREAKING: The secret to living to 100+? HIGH CHOLESTEROL! A massive Swedish study tracking over 800,000 people for 35 years just revealed: Every single centenarian had HIGH total cholesterol. The higher your LDL, the longer you live. Mind blown yet? Dr. Ben Bikman exposes the lies about cholesterol being "bad." Key findings from the Sweden AMORIS study: - All centenarians: High total cholesterol, high iron, low glucose. - Highest LDL-C = longest lifespans (backed by Dr. Uffe Ravnskov & Dr. Malcolm Kendrick). Dangers of low cholesterol: - LDL <70 mg/dL → 3X higher risk of brain-bleeding strokes. - Total <180 mg/dL → Skyrocketing cancer & dementia rates. - <150 mg/dL → Increased chronic diseases like cancer & autoimmunity. - Statins? They don't extend life—damage mitochondria & hormones instead. Why your body CRAVES cholesterol: - Builds every cell & powerhouse mitochondria. - Absorbs vital vitamins A, D, E, K. - Powers digestion via bile acids. - Supercharges immunity against infections, viruses, bacteria, pathogens—even cancer. - Fights depression, suicide, dementia & cognitive decline. - Shields from toxins, heavy metals, strokes, heart disease & osteoporosis. - Fuels ALL steroid hormones (low chol = low testosterone & libido). - Lowers all-cause mortality risk. Pro tip: Go low-carb, load up on nutrient-dense animal foods. Grass fed beef, pastured eggs, wild caught seafood...Dump seed oils, sugar & processed garbage. Target TG/HDL ratio <1.5 for elite heart health. Tight budget like me?? Seek out a local farmer, butcher & farm market & make a 'bulk large sale deal' for beef at $5/lb & eggs $4/Dz Are you ditching your statin yet? Tell me in the comments, I read every reply & do my best to respond to every question! If I miss your question...PLEASE DM direct message me! I truly care about you & your health!👇🔥

As a response to socialism, Miami will replace NYC as the finance capital and Austin will replace SF as the tech capital.

Please do NOT come work for any company I have founded or am investing in if this LMT pro-mediocracy ad appeals to you. We are deterring our adversaries to save millions of lives, and reshoring to build the next American century. Not whatever this is.

Move to Austin! It gets better very year. So many cool, world-class people are moving to Austin from SF, LA, NY, London and many other parts of the world! Austin++

Flying home to Austin, TX. American Renaissance city. Great food & music; and lots of my favorite people live in town. Many are building stadiums, clubs or other fun places. @uaustinorg, @Saronic, @neuralink, @basepowerco, @MeritFirstUS, and dozens of others bringing in stars.

Moved to ATX five years ago and found boomtown energy with bright people. Only gotten better since. Long on Austin.

Game changer. Incredible work @OpenAI team! cc: @ChrisCamillo openai.com/index/introduc…

@dottkhan good time! 🤣

@dottkhan Yes!

I learned a new financial metric tonight. It’s EBITDACC (Earnings before interest tax depreciation amortization and cost of compute). We are looking for EBITDACC positive companies. DM is open.

We have three cool announcements today: (1) @OpenAI is launching commerce in ChatGPT. Their new Instant Checkout is powered by @stripe. (2) We're releasing the Agentic Commerce Protocol, codeveloped by Stripe and OpenAI. (3) @stripe is launching an API for agentic payments, called Shared Payment Tokens. It's clear that internet purchasing modalities are going to change a lot, and we're excited to start to lay some of the foundations. Links below!

Shopify merchants will be able to sell directly in ChatGPT. We’ve been working with @OpenAI for quite some time so people can search and buy products in chat, and it’s something we’ve had a hard time keeping quiet. Rollout is coming very very soon.

It’s been a few weeks since we brought GPT-5 to Microsoft 365 Copilot, and it’s quickly become part of my everyday workflow, adding a new layer of intelligence spanning all my apps. Here are 5 prompts that show what’s now possible:

i can't think of a non-cliche way to say this, but everyone who says having a kid is the best thing in the world is both correct and still somehow understating it.

.@sama The world badly needs a Google Trends equivalent for AI queries. Marketers + investors, share + RT if you agree.

The correction will come. The long-term value? Undeniable. Thanks to @Fortune for including my perspective. fortune.com/2025/08/20/exp…

But that doesn’t mean AI is overhyped. It means the winners will be the ones who prove AI can deliver durable outcomes in complex, regulated industries.

@FortuneMagazine asked me about the so-called “AI bubble.” My take: volatility is part of every major tech cycle, but in healthcare, AI’s impact is already tangible. Cc: @ChrisCamillo @ostrohealth @AhmedElsayyad_ fortune.com/2025/08/20/exp…
