This is why I'm done being a landlord. Not worth it. The entitlement of tenants is through the roof. If Brandon owned the house, he'd likely hand wash the dishes and work through the warranty process like a responsible adult. As a renter? Me me me... Fix now!
I went a full month this summer without a dishwasher because my landlord and property manager insisted on going through the warranty process. After weeks of no movement and still no timeline, I reminded them the lease doesn’t provide the opportunity to delay repairs to pursue warranty. Still no progress. Eventually I had to tell them if they want to pick the type of dishwasher that’s in their house, they better buy a new one today. So they were forced to replace it, outside of warranty. After wasting a ton of everyone’s time and burning goodwill with their tenant by making a family of five hand-wash dishes for a month over an appliance that costs a small percentage of a month’s rent.

Since this went viral, I'll add an angle that I haven't seen mentioned anywhere. "You can literally get more in a risk free savings account than the 2.65% mortgage rate" I hate to break it to those people, but your savings account isn't risk free. An unfortunate accident and the resulting lawsuit and you'll find out just how not risk free your HYSA is when creditors can clear it out. Your paid off primary (check your state laws) is exempt from creditors and untouchable. Is the extra 1% in your HYSA worth the very real risk? Up to you. It's absolutely not risk free, however.
The only good mortgage is a paid off one Our biggest monthly expense is gone 💰

A dirty little secret is to never tip up front for DoorDash or Whole Foods/Fresh deliveries (and similar). If you remove the tip, the offer gets raised by the company anyways to make it worthwhile for a delivery. The drivers also don't see the tip, only the total offer. So your tip is mixed in and hidden, essentially jacked by DoorDash. What should you do? Remove the tip up front, then reward a good driver with a tip after the delivery. This way they get a decent offer, funded more from the company, AND your tip on top of this. Obviously the offers may start low and your delivery might be delayed while the algorithm bumps it up to entice a driver, so keep timing in mind. If you need it fast, you'll need to tip up front accordingly. In general. The more customers tip up front, the more the algorithm lowers the company paid portion. You aren't tipping your driver, you are tipping DoorDash and keeping wages low.... Tip after delivery!

Patients are addicted to their co-pays. They'll spend $2,000/mo for health insurance to make sure they only have to pay a $150 copay for an MRI that costs $350 cash... I see it all the time. It's the first concern when I mention medical sharing instead of insurance - but what about the copays! You mean I have to pay the first $500 myself for an event? Full price for the doctor?! Yeah. The doctors visit that you expect to make a $40 copay will run you $95 in cash. The $4 copay for generic drugs might run you $8 without insurance. But you'll save $1500/mo on your health plan... And people still can't wrap their heads around it.

This is a great post exploring why many Europeans, especially in countries like Denmark - worship the government and authority. And how that has played into their climate obsession/religion. I spend a lot of time there and it really is a bizarre thing to see.
I have been keeping track of the replies to my posts over the last month. More than 85% of people who push the “climate crisis” narrative aggressively in my comments are from Western Europe; specifically the UK, Denmark, Ireland and Germany as standout countries. Most of the chemtrail BS, though, is from fellow U.S. citizens. I have a theory for why this is the case: The root cause is the same, but the effect from it has more to do with cultural differences. Europeans tend to be more academically oriented and obedient than Americans. They go to college, get a degree, and are only good enough to regurgitate whatever talking points their professors gave them. They sound eloquent, but there is little actual brain power. Academia used to be a place where one could advance his or her thoughts independently and experiment at will. A college education used to have significant value. “High education” today reflects ideological conformity. Students are being taught what to think rather than how to think, and this has created a marching army of young scientists who read from the same script. In my view, these biases exist because European nations were kingdoms for centuries. Because royalty is to be respected, that authority is now vested in government officials and scholars who are viewed as sacred priests that cannot be questioned as if it we were still living in the Medieval times. Americans, on the other hand, have a more anti-establishment worldview, and most Europeans who despited royalty left there 200-300 years ago. And, over time, their anti-establishment sentiment has been passed down to us. The same educational deterioration that has taken Europe by storm has happened here. The difference is that Americans take that into overdrive and often dismiss science in general, even if it’s valid. Combine that with the fact that the U.S. federal government has lied about so many things, it’s a recipe for conspiracy theorists. The common denominator here is that the quality of education is poor. But, the cultural differences between Europeans and Americans has yielded drastically different results. Obviously, not every European thinks like a religious zealot and not every American is a conspiracy theorist, but it’s a general pattern I have noticed. That’s just how I see it, though.

I'm not a fan of RFK. But make no mistake, doctors like this are far more dangerous. She claims that Tylenol doesn't cause autism. She actually has no idea if it does or does not, and made this claim regardless because of her bias. Multiple studies link Tylenol to autism. The evidence isn't strong, but it's there. At best, we simply don't know at the moment and I'd personally suggest the precautionary principle.
The amount of dangerous misinformation coming from this administration is appalling. Tylenol use due to circumcision does NOT lead to autism. Researchers have spent years trying to understand this complex disease yet RFK is so arrogant to think that in a few months that he has the answer while citing questionable studies.

Lululemon makes clothes out of toxic recycled plastic garbage. Their clothing is literal trash. Expensive trash that poisons people. Costco's version is 97% cotton. It's funny to me that the Costco knockoff is actually far superior and safer, for 75% less money.
Oh wow this is truly shameful Costco! Does anyone know which aisle? This is so terrible I have to see for myself

Imagine dropping 35% in a day. $327k of your nearly million dollar account. All because you "do your research" on your stock picks and thought you had it all figured out. "Easily beating the market"... No time to respond like you expected. Huh. This happens to everyone picking stocks eventually. It's inevitable. The young investors don't want to listen. The index was down 2.8%, by the way. Not a concern. Will anyone learn lessons from this?

Be careful when you take financial advice from people that don't have many assets. This is prevalent on X. A lot of strategies and decisions change significantly when you have assets to protect and preserve. Likewise, you may never have many assets to protect and preserve if you follow a lot of their advice.

An excellent post about the ongoing issues with @BioLayne I'll add Robb's post as well. I agree with Robb that this appears to be a very real, uncontrollable issue with Layne. There is no reason for Layne's ongoing attacks and vitriol towards decent people in the health space whom he simply disagrees with. Especially since Layne is usually wrong. nitter.app/robbwolf/status/198680…
On the @BioLayne vs @paulsaladinomd debate that never happened. Here's what you should know. But first: 🚨Note 1: I have Paul's explicit written permission to share this text exchange between him and Layne 🚨Note 2: I feel comfortable posting it without Layne's permission because (i) he lied/lies, details below (ii) he continues to bully, harass, and posture (and I’ve gotten pinged no less than a dozen times in the last 24 hours) Preface On the planned debate with Paul Saladino on Peter Attia’s podcast... Yes, Paul declined after receiving the terms of the ‘debate,’ which seemed overly restrictive. I know this because Paul offered me in his place and received an emotional response from Layne that constitutes nothing less than a lie. Below is a post I wrote long ago and never made because I decided it wasn't worth the oxygen. I'll leave it for what it's worth because it's the truth, one Layne has abused consistently with his emotions and frank likes to avoid a serious discussion. Why am I making it now? Well, my hope is this gets him to - at minimum - sit down with @paulsaladinomd (or @ChrisMasterjohn) on @realDaveFeldman podcast... because he's made it quite clear that... to quote @BioLayne "Nick Can go fuck himself. This will be the only response I have about why I don't interact with Nick" 🚨Now... the post I held back... and the truth🚨 In the spirit of curiosity, no avatar on social media has fascinated me more than @BioLayne. You’d think that, for someone who’s clearly a successful businessman, he’d possess stronger instincts for self-preservation. Yet his public behavior suggests otherwise. So, let’s rewind, examine the behavioral history, and perform a social media autopsy on what makes this situation so baffling. A few years ago, I was generating content I knew would get Layne’s attention—most notably the Oreo vs. Statin study. Anticipating engagement, I reached out privately to build a bridge. I offered him the opportunity to review and comment on the manuscript before submission, with full acknowledgment and credit. It was a sincere attempt to collaborate in good faith. He failed to accept that the offer. But later, to his partial credit, we engaged in what seemed to be a productive group chat about a meta-analysis of human randomized controlled trials on cholesterol, lipids, and lean-mass hyper-responders. Layne appeared curious. We provided him with everything—data, context, open-access code—the whole package ht/ @realDaveFeldman @AdrianSotoMota Then came the first odd choice. Rather than collaborate or even verify his understanding with us, Layne released solo coverage that completely ignored the human RCT evidence. This was especially ironic, given his constant appeals to “human randomized controlled trials” as the gold standard of rigorous science. In that video, he also made physiological errors—errors we had already explained to him privately. He publicly asked for feedback. I took him at his word. In a **real-time response video to his coverage of our data** I corrected his factual mistakes and pointed out his omissions. (I also pointed out instances of inappropriate bullying and vulgarity in response to the negative feedback on his presentation, but at no point did I insult him personally.) Then came the stranger turn. Layne went silent. He declared he’d never engage with me again on social media. Yet, as my name began to circulate in overlapping circles, he started repeating a bizarre and easily falsifiable narrative—that I had “gone out of my way to attack him while his mother was sick.” Here’s what actually happened: Layne was actively posting about our data on Instagram and Twitter during that period. My real-time response—focused entirely on the data—simply coincided with that personal moment. I have compassion for anyone dealing with family hardship. But let’s be honest: the man was literally wearing and selling a shirt that read Data > Feelings in the very video where he misrepresented data and physiology than appealed not only to emotions but a lie to make the emotions palatable. The irony writes itself. Instead of addressing the data, he manufactured an emotional alibi—a story that let him avoid accountability while painting himself as the victim. And here’s where things got truly bizarre. Over a year later, Layne resurrected this lie publicly. Despite the fact that timelines, videos, DMs, and tweets have immutable timestamps (and witnesses), he leaned into an appeal to emotion designed to obscure verifiable facts. It’s an obvious fabrication—and a poor strategic choice. Because the chronology is transparent. The self-proclaimed “BS Crusher” had his BS crushed—and he couldn’t (he can’t) handle it. Now, every insult and every shallow flex only exposes the hypocrisy. Layne’s supposed devotion to “data over feelings” has devolved into a pitiful inversion: Feelings over Data. Does he think people can’t see it? Or has he repeated the story so many times that he’s convinced himself it’s true? I’m not sure. But it’s curious. #StayCurious Tagging some people who pinged me in Layne's @thegarybrecka and @paulsaladinomd won't debate me flexes. I can't reply there because he's blocked me for the reasons explained above. @reallyoptimized @the_meat_market @defabstar1 @thegarybrecka @insightfulposts @1Ronin_Jedi

Exactly as I had predicted and suggested. The authors were clearly silent while working through the process with the journal - nothing nefarious at all. The dose/response results from this study deeply challenges the lipid hypothesis. Doesn't mean LDL doesn't matter, but it's undeniably new and fascinating data. Should be fun to watch the debate unfold at this point, and I'll continue to follow those, and focus on those who engage in respectful dialogue. That is how things should work. Grab your popcorn. It's going to get good!
1/11) Since our KETO-CTA paper was published on April 7, 2025 there has been an undeniable and conspicuous spiral of events, leading to a strong diverse set of opinions on the data. It’s also been noted that since around April 18th, my co-authors and I have been quiet regarding criticisms rendered. I’ll speak for myself when I say this wasn’t personal my preferred approach. However, it was the strong preference of JACC Advances that we work through the preferred academic channels – namely, by responding to Letters to the Editors passed to us from the journal. Now that we’ve done so (links at the end), I’m pleased to break my silence and speak more freely.

"We're in a bubble" No, we aren't... Not even close. Do you see robots replacing nearly all service labor yet? Any robots? Robotaxi replacing most vehicles? Healthcare tech solving disease and aging? A merge between man and machine? Movies and entertainment, including games, personalized and generated on demand? Universal basic income? Colonization of the moon, Mars and beyond? Quantum computing? And so, so much more. Use your imagination, because it's all happening, fast. We are at the beginning of a massive shift towards growth and abundance that is unimaginable. And it's happening exponentially. Faster and faster. We can't build compute and energy fast enough to keep up. Where is the bubble? I expect corrections and some challenges, but I'm buying as much as I can non-stop. Real estate, stocks, crypto, etc. This is a once in a lifetime opportunity to ride this wave.

Maybe the worst advice I've ever seen on X. If you have a business, respond always if you reasonably can. Being successful in business is remarkably easy, seriously. Just do exactly what all of your competitors won't - make sure your customers know you passionately care. You'll print money. You'll also keep your biggest contracts even when you make mistakes because they'll love you so much. You have seen my products, sometimes daily. I still respond to my key accounts within minutes of them contacting me. Everytime. Even at Disney with the family. I'm also at Disney on a random Tuesday because I responded to my key accounts no matter what, any time of day.
Pro tip: Never respond to a customer after 5pm or on weekends. No matter what.
