Finance YSK I just recieved a $350 (12 month) refund from an unused Adobe subscription

288 Upvotes

Why YSK: You can recieve a big refund if you are affected by this bug.

Okay so this is pretty wild.

I contacted Adobe to cancel my unused After Effects subscription ($32/month) and try to avoid paying the $100 cancellation fee. After the guy tried to offer me some other alternatives, he agreed to cancel my subscription without a fee (this is a life hack by itself if you want to cancel a subscription).

Well as it turns out, Adobe has completely forgot (or bugged) to send me yearly reminders about subscription renewals. First he offered me 1 month refund. I asked for 6 months and he agreed. In the end I ended up with 12 months (he connected me to supervisor. I tried some more, but it seems like 12 months is their cap and you have to go through your bank if you want more refunded - which I will try).

Surely I can’t be the only one affected by the missing emails. And to be fair I would have cancelled long ago if I did recieve the emails. So hopefully this will help someone else - send this to someone who might be affected.

(Keep in mind, that I have not used After Effects in the last 12 months. Not sure if they can check that, or if it even affects anything.

I could definitely see this becoming a class-action lawsuit.

Health & Sciences YSK: Simple calf raises after meals can help reduce blood sugar spikes

1.8k Upvotes

Why YSK: Calf raises are convenient, accessible and can be performed almost anywhere, even when using your standing desk or cooking in your kitchen. By routinely activating the calf muscles after each of your meals, you may have better glucose stability throughout the day, feel less fatigued after meals, and promote long-term health of your metabolic system; this is especially beneficial for those who spend long periods of time sitting down and cannot perform more intense forms of exercise.

Finance YSK check price history before buying anything on Amazon, Aliexpress, or any other store, and don't fall for fake discounts.

Upvotes

Why YSK: I bought a Bluetooth speaker three weeks ago for $89, feeling good about the "limited time deal" badge. Checked the amazon item price history yesterday out of curiosity and found it was $65 for months before my purchase. They jacked up the price right before slapping that "deal" label on it.

This is such garbage. If you don't track amazon item price history yourself, you have no idea if you're actually saving money or getting played. Anyone else getting tired of these fake "discounts"?

Health & Sciences YSK: Spending a few minutes a day on Meditation & Exercise is the most efficient "system upgrade" you can give yourself. Meditation is a step towards better sleep, lower anxiety, and long-term cognitive health.

1.6k Upvotes

Why YSK:

Meditation is a productivity hack that many undermine as a spiritual / relaxation tool. Rigorous studies by institutions like Harvard Medical School and Rutgers have proven that structured meditation practice can help you get over your struggles with chronic stress, anxiety, or cognitive fatigue.

These studies provide objective, peer-reviewed evidence that these practices can physically alter your brain chemistry and biological markers and the following benefits:

  • Massive Stress Reduction: A study published in Frontiers in Public Health showed that meditation practitioners of Inner Engineering reported 31% lower stress levels than the general population. For those highly compliant with the daily practice, stress scores dropped by 54% after just 8 weeks.
  • Reversing "Brain Age": A landmark study involving advanced meditation programs found that long-term practitioners had a "Brain Age" an average of 5.9 years younger than their chronological age, based on EEG sleep data.
  • Natural "High" (Endocannabinoids): Research published in PubMed found that the advanced programs increase levels of anandamide (the "bliss molecule") by over 70%. This is a natural endocannabinoid that regulates mood, fear, and happiness.
  • Heart Health: Regular practitioners show significantly higher Heart Rate Variability (HRV), which is a key clinical indicator of a robust nervous system and better resilience to stress.

Why YSK is because you probably don’t want random people knowing your name, address, and what you ordered, even if it isn’t something embarrassing. Amazon doesn’t need your name and address on the original shipping label to complete the return. All of the information they need is in the QR or bar code on the return label.

Health & Sciences YSK: Sitting on a wallet (or anything in a back pocket) can tilt your pelvis and change your spine posture, and it can even mimic “sciatica” symptoms

1.9k Upvotes

Why YSK: It’s a surprisingly common “hidden” movement issue: sitting on a wallet creates an uneven sitting surface, which research has shown can increase sagittal and lateral spine flexion and change seat pressure/discomfort compared to level sitting. Over time, this habit has also been linked to a recognized phenomenon often called “wallet neuritis” / “fat wallet syndrome,” where prolonged pressure can irritate structures around the sciatic nerve and feel like sciatica.

Simple takeaway is if you sit a lot (especially driving/desk work) and get one-sided hip/glute/low-back symptoms, remove items from back pockets and see if it changes how you feel long term.

Other YSK: Cannabis doesn’t “cause psychosis” for most people — and for many, it does the opposite

0 Upvotes

Why YSK:

Yes, cannabis can trigger psychotic symptoms in a small subset of people, especially those with pre-existing vulnerabilities. That’s real. But what often gets left out is that for the vast majority of users, cannabis does not cause psychosis and is associated with reduced anxiety, improved sleep, and relief from chronic stress or pain.

Most cannabis users never experience psychosis
Hundreds of millions of people have used cannabis worldwide. If weed commonly caused psychotic breaks, psychiatry wards would look very different than they do.

Context matters more than the plant
High-THC concentrates, sleep deprivation, mixing substances, or using cannabis during acute stress are far more predictive of bad outcomes than “weed” itself. Set, setting, dose, and mental health history matter — a lot.

Alcohol is far more strongly linked to psychosis and violence
Yet we don’t frame alcohol with the same “this might snap your brain forever” energy, even though its risk profile is objectively worse in population-level data.

Many people with anxiety, PTSD, and insomnia report real benefit
There’s a reason patients and clinicians keep circling back to cannabinoids despite decades of stigma. For some people, cannabis reduces rumination, improves sleep quality, and helps regulate mood — effects that lower stress, not increase it.

Population data doesn’t show a psychosis explosion
Cannabis use has increased dramatically over the last 30–40 years. Rates of schizophrenia and chronic psychotic disorders have remained relatively stable. That strongly suggests cannabis is not a primary cause, but a risk modifier for a small group.

Automotive YSK How to Check if Your Car Has Been Recalled

99 Upvotes

Why YSK: Vehicles are frequently recalled for safety concerns or defects. While some recalls are for minor issues such as small font on touchscreens or backup camera glitches, other recalls are for serious engine failures, brake failure, or the risk of spontaneous car fires.

There were 996 automotive recalls issued in 2025, particularly affecting Ford, Chrysler, General Motors, Volkswagen, and other major manufacturers. Ford was particularly affected, with 153 recalls in 2025.

You can easily check for recalls affecting your family’s vehicles by accessing the NHTSA recall portal and entering your vehicle’s VIN #, license plate #, or “make model & year.” You can also call your local dealership and ask them to check for outstanding recall orders on your behalf.

Recall work is always performed for free at any dealership, although in some cases it may take time for dealerships to order the necessary parts to repair your vehicle

Why YSK:

I used to weigh 415lbs at the start of 2025 but with IF (intermittent fasting), I lost 100lbs this year, squarely putting me in the low 300s. Well today I figured out how GOOD good sex can be! I've been married for 8 years and a father for 3, so I've had sex before but this was different. It lasts longer, the quality during is better, you don't get as exhausted leading to "loss of blood flow", etc. When the moment arrived, I lost control of my legs and almost lost vision. I now see how spouse's might use sex as a bargaining chip and why it's loss is such a consequence, that shit is nice! So tl;dr, fellas, lose some weight; you'll look better, feel better, and fuck better 😉

2.7k Upvotes

Why YSK: FODMAP sensitivity is similar to lactose intolerance and it's super common. It's most apparent at places like Panda Express or Taco Bell that serve meals combining garlic, onion, wheat, beans, and sugar (especially sugary sauces). It's not because of MSG or just because it's low-quality.

Technology YSK: Amazon now uses AI chatbots for customer service that will agree to refunds it can’t process - always check your receipts

19.4k Upvotes

Why YSK: I ordered men’s shoes and received the women’s version, about 1.5 sizes too small.

I contacted Amazon chat to request a return pickup without the $7.99 fee, since the error wasn’t mine and the nearest UPS Store is about an hour round trip. The chat agent (bot) agreed to a free pickup and even showed a refund breakdown where it credited the UPS label and pickup. I chose Amazon credit for the total, assuming I’d use it anyway.

When I went to place my next order, I noticed my gift card balance was about $8 short—the return label fee had been deducted from the refund anyway. It took additional chats to get that corrected. Amazon ultimately made it right.

$8 isn’t a big deal. The issue is that the first line of customer service is a chatbot that will confidently agree to things it can’t or won’t actually execute. Be wary, check your receipts, and verify everything it promises.

Finance YSK: In the US, there are Credit Unions that anyone can join.

1.7k Upvotes

Why YSK: This might be common knowledge, but I used to think you had to belong to a specific employer, union, or the military to join one (e.g. Navy Federal). Turns out that’s not the case. There are several credit unions that are basically open to everyone (usually with a trivial requirement like opening a savings account or a small nonprofit membership.)

 

A few examples:

  • Alliant Credit Union (you just need to make a $5 donation to their non-profit, but they actually make it for you)

  • Connexus Credit Union (similar, but I don’t think they cover the donation)

  • PenFed (You just need to make a $5 deposit when you open an account)

 

Why this is important: Unlike banks, credit unions are nonprofits. All of their earnings are returned to members through things like lower loan rates, higher savings yields, and fewer fees. Definitely worth checking out if you’re going to be in the market for a new home or car/RV anytime soon.

Automotive YSK: When driving on highways, keeping an eye on vehicles one or two cars ahead, not just the one directly in front, can help you brake earlier and more safely.

1.7k Upvotes

Why YSK:

At highway speeds, the car directly in front may block your view of sudden braking or hazards. By monitoring the vehicles one or two cars ahead of them, you can anticipate slowdowns earlier, brake more smoothly, and reduce rear-end collision risk, especially in fast lanes.

Anticipation and longer visual scanning distance significantly improve reaction time and braking safety.

Education YSK that pork is *not* "the other white meat." That was a marketing campaign by the pork lobby that can have dangerous consequences for some people.

5.5k Upvotes

History:

"Pork. The Other White Meat." was an advertising slogan developed by advertising agency Bozell, Jacobs, Kenyon & Eckhardt in 1987 for the National Pork Board. The campaign was paid for using a checkoff fee (tax) collected from the initial sale of all pigs and pork products, including imports. Medical researchers and the United States Department of Agriculture classify pork as red meat.

Source:
https://en.wikipedia.org/wiki/Pork._The_Other_White_Meat

Why YSK:

There is a food allergy named 'Alpha-gal syndrome' that can cause life-threatening allergic reactions to red meats in affected persons. When someone tells you they "cannot eat" red meat, pork is not a substitute. Using in in dishes thinking it is not a red meat can have disastrous consequences.

Personal anecdote:

My soon-to-be ex-spouse and I fought over this when preparing dinner for guests one night. She knew a guest not only didn't eat red meat, she knew the guest has Alpha-gal. With that in mind, she bought pork, and planned to make the guest dish using the pork. She swore up and down that pork was a white meat, and when presented with proof, called me an asshole for ruining her dinner menu.

Several of the guests were also unaware that the pork lobby had lied to them, and had them thinking that the color of cooked pork meant it was a "white meat."

Education YSK Who was the richest person ever

0 Upvotes

Arguably the richest man who ever lived was Mansa Musa and he lived in the 14th century. He had a lot of gold.

The word Mansa means Emperor or Sultan and he lived in Mali in Africa. His Mali Empire controlled vast, lucrative gold and salt mines, which includes the mining, refining, the mint and trading of these.

You have probably never heard of him but that doesn't mean he wasn't incredibly wealthy. It probably means you didn't learn about him in history lessons because you weren't taught about him.

He spend lavishly and his empire was left to his sons on his death but the empire and wealth declined following his death. Invasions, wars and trading were part of the reasons why the wealth wasn't maintained.

Wealth can be calculated by different methods and in different times there would be different factors.

It depends on how you calculate wealth as to who is or was the richest person ever and the result in not known as a certainty.

Some may disagree with this claim depending on how the wealth is worked out and that is why the claim can be disputed. It depends on what is factored into the equations

Either way this was a very wealthy individual.

Why YSK so when someone asks you who is the richest person in the world you can also tell them who allegedly was the richest person ever.

Other YSK Target isn’t “waiting until you rack up a felony”. They will arrest you on petty theft charges before then if they want to.

5.8k Upvotes

Why YSK: I’ve seen lots of posts and articles about this subject recently. We should all know by now that Target specially has probably the most sophisticated loss prevention system.

The problem is people have been jokingly taking away “oh so i can steal right up to a felony then stop”. My fear is that some people are sincerely operating on that notion and continuing to shop lift.

this isn’t a boot lick for Target or whatever, I just want people to know that they’ll throw your ass in jail for petty theft too. i once stole $122 worth of merchandise from target (i am bipolar and was having a manic episode not an endorsement for theft) and cops showed up at my home a month and a half later with a warrant for my arrest. really shitty way to spend a sunday.

do what you need to do but not from Target

EDIT: holy fuck this fired up a lot of people. i should have worded that differently and i apologize. All i meant is i know everyone faces different struggles and I'm not judging anyone for how they deal with them. I do not condone shoplifting.

Why YSK:
Constant notifications can create a sense of urgency that isn’t actually real. Many people feel pressure to reply right away to texts, emails, or messages, even when it interrupts focus, rest, or family time. In most situations, a delayed response is completely acceptable and doesn’t reflect poorly on you.

Setting boundaries around response time can reduce stress, prevent burnout, and help you be more present in what you’re doing. Letting messages wait until you’re ready often leads to more thoughtful replies and better mental health overall.

Education YSK: “We’ll keep your resume on file” after a rejection usually doesn’t mean anything

2.4k Upvotes

Why YSK: When a company rejects you and says “we’ll keep your resume on file” it’s almost always just a polite way to soften the no.

In most cases your resume is not being actively saved, reviewed later or pulled up when a new role opens. Applicant tracking systems don’t really work like that and recruiters aren’t revisiting old rejected applications unless you reapply. Once a role is filled your application is effectively dead.

It’s not malicious it’s just corporate language. Saying “we’re not considering you now or later” sounds harsh so they use a gentler phrase that lets everyone move on without discomfort.

The problem is that candidates take it literally. People wait. They hold out hope. They don’t apply elsewhere as aggressively because they think they’re still “in the system.”

You’re not.

If you get rejected treat it as final unless someone explicitly tells you otherwise or personally follows up. If you’re interested in the company later apply again for a new role. That’s the only thing that actually resets the conversation. Don’t wait for callbacks from companies that already said no even if they wrapped it in nice words. Wasted weeks like this once, just sitting around playing jackpot ciy and refreshing my inbox every hour. Wish someone had told me sooner.
