- Nearly 1 in 3 American adults now take vitamin D, but Dr. Stasha Gominak says many of them are taking it wrong, and that done carelessly, supplementing can leave you worse off than before.
Dr. Stasha Gominak practiced neurology for over 20 years. She earned her MD from Baylor College of Medicine and completed her neurology residency at the Harvard-affiliated Massachusetts General Hospital. After working with her own patients, she believes that nearly everyone struggling to sleep shares the same hidden deficiency, a conclusion she published in 2 papers and built into RightSleep, the method she now teaches full time.
She explains:
◼ Why she believes your skin is the best producer of vitamin D, and why she says no amount of pills or salmon can replace it
◼ Why she believes insomnia isn't a behavior problem but a chemical deficiency, and what she thinks changed when we moved indoors
◼ The role she says your gut bacteria play in producing your B vitamins
◼ Why she believes taking vitamin D on its own can burn through your B vitamins, and what she says happened when she tried it herself
◼ Why she connects the rise in conditions like ADHD, depression, fatty liver and diabetes to the same period, and what she thinks links them
◼ Why she considers supplements a form of biohacking, and just as risky as any drug if you get them wrong

Matthew McConaughey: https://www.instagram.com/officiallymcconaughey/URGENT UPDATE - Iran War Expert: 70% Chance US Sends Troops To Iran THIS WEEK! | Robert Pape
2026-07-23 | 1h 40 mins.The War everyone assumed was over may be about to become something far worse than we could have expected. Professor Robert Pape explains exactly why the deadliest phase of this war is still ahead, and how this could trigger a wave of terror across the world.
Robert Pape is a Professor of Political Science at the University of Chicago and director of the Chicago Project on Security and Threats. A renowned political scientist, he has advised every White House since 9/11 on military strategy and is the author of the upcoming book “Our Own Worst Enemies: America and the Age of Violent Populism”.
He explains:
■ Why the US bombing campaign failed to topple Iran’s regime, even after killing its top leaders
■ How Iran seized control of 20% of the world’s oil supply within days of the war starting
■ Why the failed agreement handed Iran a path to becoming the most powerful country in the region
■ Why both China and Russia gain from America staying stuck in the Middle East
■ Why he thinks US ground troops could be next
■ Why he thinks there will be a clash between Congress and the president over who really controls the power to go to war

HeyGen - https://heygen.com/doacThe Man Who Made $100M Before 32: The Secret Was To Stop Letting Them Control Me | Alex Hormozi
2026-07-20 | 2h 22 mins.Every founder is being told to build an AI company. Alex Hormozi says almost all of them will be gone within months, that the best move is the exact opposite of what the market is saying, and that in a world of AI the only moat left will be reality and your reputation.
Alex Hormozi is a entrepreneur, investor and author. He is the co-founder of Acquisition.com, a portfolio of 16+ companies generating over $250 million a year, and the author of the $100M series: '$100M Offers', '$100M Leads' and '$100M Money Models', whose 2025 launch sold 2.9 million copies in a single day and broke the Guinness World Record for the fastest-selling non-fiction book in history.
He explains:
◼ Why the practical businesses, like plumbing, are the real opportunity, not the ones built on top of AI models
◼ Why delegating your hardest thinking to a machine makes you weak
◼ Why reality and reputation are the only moats AI can't erode
◼ Why revenue retention matters more than marketing or sales
◼ Why marrying his wife Leila was the best financial decision he ever made, and how the right partner changes your odds
◼ He opens up about one of the hardest years of his life, in the same year he made more money than ever
