@Mr_Husky1 Run! Wedding with prenups last longer without prenups when one or both have an inheritance or their own wealth!

I’m about to get married, and my fiancé knows I have an inheritance that was left to me by my grandparents. It’s in my name only, and I’ve been saving it for years. Now he’s saying that before we get married, I should put the entire inheritance into a joint account so we can “start fresh together,” or he doesn’t think we should go through with the wedding. I’m 36 already and this is something my family worked hard to leave me. I’m torn between wanting to build a life together and feeling like I’m being pressured to give up something important to me. What do you think I should do? By isitmeaitah

@MDDH08 @MatrixMysteries It is billed amount that needs reigning. No politician wants to touch this issue as they will get booted out by lobbyists even when solution is simple. Limit amt billed to 3x the #medicare reimbursement code! Hospitals claim they lose 20% on medicare - 3x is very generous then.

@MatrixMysteries It’s itemized here. 105k to capture maximum reimbursement from all insurance carriers. 77k “discount”. And 26k paid by insurance (it might cost this much, again due to inflated costs from regulation). $1200 paid by patient.

An American woman needs a hysterectomy. Without insurance, the bill is $105,129.74. The EXACT same procedure but done in Mexico costs $3,500–$5,000 That’s over a $100,000 difference for IDENTICAL care, just miles apart. This isn’t a pricing problem — it’s exploitation.

@_Johoshua @CollinRugg This is a bold move. Data centers increase water and electricity bills of all residents, and hence subsidizing billionaires like we all do for pro stadiums. Noise pollution. Tax revenue - what revenue! Employ 30 to 50 people once construction is finished.

And that county will now be out $400-$500 MILLION in tax revenue over 20 years. That could of rebuilt all the counties public highway infrastructure and a couple of water towers and some schools and replace the Waste Water plant, but instead we're going to keep our farm and stay fat as fuck and barely able to hobble around braless with a stick. PS: I know what I'm talking about my company is part of a $7 BILLION dollar Data Center Project.

NEW: Kentucky family rejects $26 million offer to convert part of their farm into a data center despite the offer being about 10 times the going rate for farmland in the area. "If it's my way, I'll stay and hold and feed a nation. 26 million doesn't mean anything." "As long as I'm on this land, as long as it's feeding me, as long as it's taking care of me, there's nothing that can destroy me if I've got this land." Video: Local 12 WKRC

@miniapeur Don't listen to this advice at all.

I hear many prospective PhD students say things like, “Wow, imagine being advised by [insert some famous professors].” Yeah, but actually, the more famous they are, the less likely you are to have much interaction with your advisor. It’s typically much better to have a rising-star professor as your advisor if you want real supervision and support.

@PhD_Genie Always learning side!

As an academic, what is your personal philosophy? (In 3 words or less)

@MatrixMysteries Could not have contributed more than 325K each even if they worked 45 years at the max level. SS is an insurance. Let the low income people have some peace in their old age.

An American woman loses both parents and goes through their Social Security records. They paid in for DECADES — nearly $1,000,000 combined. Her dad died before collecting a CENT. Her mom only received about $32,000 a year for four years. That’s not a safety net. It's a SCAM.

@BrianPrescott48 Amazed at how just a $500 calorie deficit works. If you cannot do it, GLP1 may be what your provider may suggest. If calorie deficit did not work, GLP1 should not work either.

High blood pressure, high blood sugar, bad cholesterol, and belly fat—it’s not four different problems. It’s one problem: Metabolic Syndrome. It’s time to stop playing whack-a-mole and address the root cause with Citrus Bergamot + Berberine. 1. Whack… twitter.com/i/web/status/2…

@jmdenouden @MrDanielBuck Give a couple of passes and it will be all good. Life happens to kids too!

@MrDanielBuck How did parents respond? I would like to move in this direction, but don't know how it will go over

Later into my teaching career, I set a simple classroom rule: No late work, none Kids didn’t start failing en masse Instead, they all started turning their work in on time, no rush of late assignments at semester’s end, fewer students falling behind It was a more humane rule

@ThrillaRilla369 Thanks to Jack Welch and Milton Friedman to start the modern day slavery.

It's wild how society accepts leaving kids at daycare 40 hours a week just to commute to a job that funds the daycare, the car, and a house you're rarely in. We're basically grinding to pay for a life we barely get to experience.

@cecegkh So @Delta changed my flight 3 months in advance. Then tells me that I will hence miss the connecting flight. Ask me to change flights online and we’re going to charge me $300 extra. 3 hours of my weekend afternoon in chat box and problem was resolved. They could do better.

Frontier Airlines overbooked several flights that day, not an uncommon occurrence on flights, but what they did next was crazy. Instead of asking for volunteers to fly at a later time with compensation, they just began denying people seats and telling them that they were “late” for their flight. (They had been in that line for over an hour and a half.) Now here is where it gets even crazier. They were offering to put those removed from the flight on a later flight, but it would cost them an EXTRA $100 to do so. Would you just pay the $100 or would you demand a refund for your ticket? Obviously the young guy in the video is pissed. Is he in the right or is Frontier?

@asanwal Do we ever ask employers to be accommodating. I do not know why. Because they have trained us to be enslaved to the job.

@JoyceCarolOates When push comes to shove, if your kid gets accepted into the top 15 univs, you will do everything to send them there. Go to the top univ - the privilege and network is worth it. If it were not, people would not be chasing them.

sorry to be insistent & repetitive, but there are many more than 15 "top" universities & a number of excellent small liberal arts colleges. feeling sorry for young persons who have been virtually brainwashed to think that their lives depend upon being accepted by a "top" university. there is so much in American culture to discourage & depress young people. at least, when some (of us) were college-age, the world seemed open & welcoming; scholarships for both science & the humanities abounded; there was no Internet, thus no obsessive focus on "top universities"; there was no hydra-headed AI looming ahead...

@joelwatsonfish It is because at any R1 university they are obsessed with grants, papers/citations and PhD students. Rest is whatever will be will be!

I’m a department chair at an R1 university. I have not heard any professor express this sentiment.

@Sally_Sharif1 Old saying - why use dumbbells in the gym when a forklift is available. We are moving our students directly to the forklift!

I just gave a closed-book, pen-and-paper midterm exam in my 300-level course at UBC with 100 students. All exams were graded by an experienced graduate-level TA according to a rubric. *** The average was 64/100.*** My class averages at UBC are usually 80-85. Context: • This was the first midterm, covering ONLY 4 weeks of material. • Students had a list of possible questions in advance: no surprise questions. • Questions included (a) 3 concept definitions, (b) 3 paragraph-long questions, and (c) a 1.5-page essay. • I have taught this class multiple times. Nothing in my teaching style changed this semester. • We read entire paragraphs of text in class, so students don't have to do something on their own that wasn't covered during the lecture. • Students take a 10-question multiple-choice quiz at the end of every class (30% of the final grade). • Attendance is 95-99% every class. Attention during lectures and participation in pair-work activities are very high → anticipating the end-of-class quiz. *** But unfortunately, I suspect many students are not reading the material on the syllabus. They are asking LLMs to summarize it instead.*** After the midterm, students reported: • They thought they knew concept definitions but couldn't produce them on paper. • They thought they understood the arguments but struggled to connect them or identify points of agreement and disagreement. My view: It might be “cool” or “innovative” to teach students to summarize readings with ChatGPT or write essays with Claude. But we may be doing them a disservice: reducing their ability to retain material, think creatively, and reason from what they know. If you only read what AI has summarized for you, you don’t truly "know" the material. Moving forward: We have a second midterm coming up. I don't know how to convey to students that the best way to do better on the exam is to rely on and improve their own reading skills.

@DrAlmarielao The blame lies on having to work 70 hour weeks. Friedman gave us shareholder primacy. Welch showed CEOs how to enforce it. The result? The American worker became chained to the job!

A mother who works about 70 hours a week received a school calendar listing all the holidays, early releases, and teacher planning days. Curious, she used ChatGPT to organize every day her kids would be off from school during the year. When she saw the full list, she was shocked by how many days there actually were. Her husband stays home with the kids, but she started wondering how families with two full-time working parents manage all those days off. School schedules can look manageable at first glance, but when you add up all the days off, it really highlights how challenging childcare logistics can be for many working families. How do households where both parents work full-time handle the large number of school holidays, early release days, and breaks during the year?

@Villgecrazylady Here is the deal - there are three tiers of software engineers 1) work for a company like Google 2) work for a big bank, and last 3) work at a university. So there you have it. But univ staff suffers as they develop internal products based on archaic software.

How is it even remotely possible that a university which graduates about 1,800 students each semester with degrees in software engineering needs to look outside our country for a software engineer?

@kkmaway It is all about no-hassle service. Been with @StateFarm now for 41 years (I know it costs more) and never faced an issue that needed to be resolved beyond the customary! Bundling helps a lot!

I used to auto renew my auto policies. Didn't want to go thru all the hassle of getting a new carrier. That was a mistake, I am finding out. 23% lower from a better rated carrier. SMH

What could go wrong with this approach? 😂axios.com/2026/03/05/ira…

@El_Mountain_Man @bankertobuilder Trees are bad news for underground pipes.

@bankertobuilder Why are there no trees? Seems it would be mandatory for a place called pine ridge...

This is the new community we're building 85 miles southwest of Cleveland 1,650 beautifully crafted single-family homes starting in the low $800s We call it the Meadows at Pine Ridge Bluff Creek We've showed this rendering to a few prospective buyers and many of them cried when they saw the natural beauty of this development Breaking ground next week. The first homes will be ready by late April thanks to the efficiency of our proprietary building process. Excited for this one!
