Why YSK; even a small residual amount on your finger tips can be fatal for them

Why YSK: With the rise of DIY home repair videos, many homeowners try to fix a jammed or broken garage door themselves. This is incredibly dangerous. The torsion springs (the thick metal coils sitting above the door) are under immense tension because they carry the entire weight of the heavy door. Knowing when to put the tools down and call a professional can literally save your life or prevent a catastrophic injury.

If a spring snaps, or if your wrench slips while you are trying to unwind or adjust it, the stored energy is released instantly. The metal will violently whip out, acting like heavy shrapnel flying at lethal speeds. It can easily crush your skull, shatter bones, or amputate fingers.

This is one of the very few home maintenance tasks where you should absolutely swallow your pride and call a professional technician. No YouTube tutorial is worth losing your life over. If you see a broken coil or a slack cable, unplug the garage opener and do not touch the hardware.

Psychological reactance is the resistance people feel when they believe their freedom to choose is being threatened. For example, constantly forcing a child to do something may make them more determined to refuse, even if the request itself is reasonable. Giving them explanations and some freedom of choice can sometimes reduce this resistance and encourage cooperation.

Why YSK:

Understanding psychological reactance can help you avoid unnecessary power struggles with your children. Instead of relying exclusively on orders and punishments, you can encourage cooperation by respecting their autonomy, explaining your expectations, and offering reasonable choices. This doesn't mean letting children do whatever they want; it means understanding that how you communicate a rule can influence how they respond to it.

Why YSK: If you've ever covered your address, account number, or other personal information with a black rectangle before sending someone a PDF, you might want to know this.

Depending on how you edited it, you may have just placed a black box over the original text without actually deleting anything.

In some PDFs, someone can literally highlight the blacked out section, copy it, and paste it somewhere else to see what you were trying to hide.

If you're sending anything with sensitive information, use an actual PDF redaction tool that removes the underlying content. Don't just draw over it.

And if you want to check whether something was properly redacted, try copying the covered area yourself before sending it.

Why YSK: Not life-changing but it can save you a little bit of money.

Insurance companies charge more if they bill you monthly compared to if you pay for the entire duration of the policy upfront in one go. Sometimes, the difference is nominal or nothing, but other times, it's actually significant. So if this is something you can afford to do, you should check if a discount is offered, and if it is, take it.

This doesn't affect your cancellation rights. If you cancel an insurance policy despite having paid for it in full, the insurer will mail you a prorated refund.

This tip works in the US with several major insurers.

Your iPhone allows you to send voicemails to a computer via airdrop, email, or various other ways through the 'Share' icon on every voicemail in your inbox.

They can then be saved to a hard drive or whatever more permanent means you prefer - or uploaded to iCloud. This creates a little more safety/permanence than just leaving them sit on a phone.

Why YSK: I have saved dozens from my mom, dad, brothers, and other special people in my life. When they pass you will have little gems to remember them by, and hearing their voice can be cathartic.

Take care, everyone!

Why YSK: If you remember reading something online but can't remember the website, you don't necessarily need to remember the title or URL.

In many browsers, you can search your history using words that appeared on the page. Your browser may have saved the page title, URL, or other indexed information that makes the page easier to find.

For example, if you remember reading an article about a specific programming technique but only remember the phrase "vector database", try searching your browser history for that phrase.

This can be surprisingly useful when you visit dozens of pages a day and later think:

"Where the hell did I read that?"

Why YSK: how to save over $100.00 to replace. The part that's pressed to open the car broke off, so there's a hole showing what gets pressed inside, probably with a spring on top that is no longer there. I use an eyeline pencil with the top on to press the inside & car door opens.

This approach will work on any button using anything that fits in the hole.

Why YSK: Many think they are the golden feelings one should have all day. With feelings such as clarity, energy. And they think being "tired" is something bad.

The confuse being "tired" when it is actual your body saying "I need relaxation".

They confuse "energetic" with being in fight and flight mode, which is not true good energy.

They confuse "happy" with taking drugs or doing something that is just a temporary high.

This is ALL over and everyone is confusing their reactions like this. I especially notice it when it comes to diet. Many who do keto or fasting diets say "I feel so energetic and clear minded".

Yeah I wonder why. Do you know what your body does when it starves? It basically goes into hyper drive and pumps out all good chemical it got left to help you find food before it dies.

No shit you feel a lot of productive emotions, it is literally how you are built and is what stress is!

What they don't tell you is that studies have found there are more conflicts when people are fasting during Ramadan for example and see correlation to worse diets. Many criminals have very bad eating patterns too where scientists suspect this is a connection.

The most dangerous part is when they get lost in this. Then they are stuck in this mode and whenever they change diet, they think "Oh well, look, now I am tired and sluggish".

No....your body and mind is recharging after using all available resource to help you from starving!

But yes, the most famous mismatch when it comes to diet: Bad carb diet (coca cola and fastfood) = good carb diet. You can also be sluggish because of bad diet. But fasting or keto diet is not always the best alternative long term.

Many feel better on fasting diet because they stop eating shit. You can eat a paleo diet and feel very good that includes a lot of carbs.
