The HR department at your company is the company's advocate they are not your advocate.

Everyone should know that, very often, they are just wrong. And that’s ok. We all are.

The more ready you are to really accept that you could be wrong about anything, and admit when you are wrong about something, the better you will make your own life, as well as the lives of those around you.

You can only help people who want to be helped. That goes for yourself, too. You can't help yourself until you actually have the desire to improve.

The ducks at the park are free. Like you can just take them.

• Exercise grows your hippocampus
• So do antidepressants according to recent research
• Small hippocampal volume is an excellent predictor of depression and anxiety
• Exercise grows your hippocampus, in a dose-dependent way
• Exercise grows your hippocampus

This is the most important fact I have ever learned.

That "coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, can have lasting effects on nearly every organ and organ system of the body weeks, months, and potentially years after infection (11,12). Documented serious post-COVID-19 conditions include cardiovascular, pulmonary, neurological, renal, endocrine, hematological, and gastrointestinal complications (8), as well as death.".

This is true regardless of symptom severity or health status, every person is at risk. I think most people really aren't aware of this, they absorbed the narrative that it's gone, mild, only kills/harms the vulnerable, etc. This isn't really their fault, there are a lot of factors that have led people to that belief, but people should know their lives and livelihoods are much more at risk now than 4 years ago.

And that this isn't inevitable, there are simple methods of disrupting transmission and protecting yourself and others. COVID-19 is here to stay (unless we do something about that) and it has impacts on every person infected and on society at large. That shouldn't mean folks accept illness and worse quality of life. We adapt and adopt precautions in our life to reduce long-term health impacts, like we've done before with many other illnesses that plague humanity.

The gas gauge tells you which side the filler is at on a vehicle.

Drowning is very fast, seconds not minutes like in the movies. People in distress can take minutes before they are actively drowning. Active drowning is silent, they will not be yelling for help. It looks like the person is "climbing" or pushing down at the water. They will be vertical in the water and may be "bobbing", going underwater and resurfacing. They will have their head tilted back parallel to the surface of the water.

If you see someone go under in open water keep looking at where they went under while calling for help, don't take your eyes off it. If you are the only one who saw them go under, your job is to direct others to where they went down. In open water it's very hard to find people because the bottom isn't visible.

Something that applies when you get a little older - if you’re in a relatively specific job field, don’t burn your bridges at a job you’re going to leave. You never know who will be sitting across the table from you at the interview, at the meeting table, on the job site. People in the same field tend to move around in the same jobs as you. If it’s someone you burned, you may not get the job, or if you do, it could be pretty miserable.

Bleach + vinegar = toxic chlorine gas that can be lethal.

Not sure how many people know this but I was in my mid-20s when I found this out, luckily not the hard way.

Unless you are wealthy, if you think life is to expensive you should ask for more taxes, not less.

The issue is not your net income, but wealth redistribution and solidarity.

Magnetic USB connectors are a thing and can save your cables/devices not just from wear and tear (unplugging/replugging constantly) but also from cables being tripped over or otherwise pulled. Highly recommended if you're using VR! Sadly there are no standards to these.

The cable is the weakest link of Earbuds for durability.

IEM's with replaceable cables are readily available and getting very cheap & good these days (e.g. Moondrop Chu 2, Truthear Hola, etc)

Keyboard shortcuts and basic computer knowledge. I'm in college and just existing with tech illiterate people is maddening.

One for people in the US:

You aren't taxed at the higher rate for all of your income when you get a raise that puts you in a higher tax bracket, only the part that is in the range of that bracket specifically. The rest of your income below the bracket is taxed the same as before.

I've seen a lot of people decline promotions and raises over this, and bosses are very happy to let you continue thinking that's how it works.

Not sure if that counts as not common knowledge, but a lot of people I know didn't know it before.

When you're about to face a high risk, high reward situation, you should willfully, willingly start to hyperventilate, as this helps your brain ...

NEVER take any stranger's advice on the internet as credible without checking it with a specialist. This is especially true when said advice relates to your health and/or safety.

Most microwaves can be muted so the button pushes are all silent. You will have to look up how to on each microwave model but almost all models have a mute option.

What wasn’t reasoned in, can’t be reasoned out. Many people who suffer from conspiratorial thinking need help and support more than evidence and debate.

Cement is highly alkaline. If wet cement comes in contact with your skin, it can cause third degree chemical burns. So don't write your name in wet cement like Bart Simpson.

In Windows 10 & 11, window+shift+S then draw a box to grab a quick, pre-cropped screenshot. It goes to your clipboard for easy paste and you get a notification you can click to view and save to file.

Bonus: use window+L at work to lock your desktop, preventing shenanigans.

Tires can get damaged internally and the only real way to tell is to dismount them from the rim. If there is internal damage they can potentially explode while being filled with air.

I see a lot of people filling up their tires while sitting straight infront of them and if they do explode it explodes straight outward. My tip is to connect the air gauge and then stand of to the side while filling, just in case.

Mitochondria (the famous powerhouse of the cell) is a symbiotic bacteria that became so entangled with our cell that neither can now live without the other. Sorry to everyone who knows, in some regions this is not common knowledge. Knowing this makes your life immensely better because it's such a cool fact.

Use windows + p to change the presentation settings on a laptop when connecting to a monitor or audio / video system. This lets you quickly change between laptop, dual display, and extended desktop.

Windows + x and then b brings up a menu where you can turn on "presention" mode, preventing the laptop from going to sleep during a presentation.

Cars are way more expensive than you think, and getting rid of it will make you happier and way wealthier.

ALWAYS CALL 911 FIRST IF YOU'RE SUSPECTING SOMEONE IS HAVING A HEART ATTACK!

That being said though:

You can save a life by always carrying around aspirin. Aspirin prevents platelets from clotting, which is very useful when someone is suffering from a heart attack. It's even one of the first medications first responders often use when someone is having a heart attack. After you've called 911 have the person chew on and swallow aspirin, making sure they're not allergic.

The act of chewing makes it so the aspirin is absorbed quicker. Stay with the victim until emergency services arrive and tell them you've given the person aspirin and the dose. This is useful information for them to know.

P.s. Here are the signs someone might be having a heart attack:

Chest pain or discomfort;

Shortness of breath;

Pain or discomfort in the jaw, neck, back, arm, or shoulder;

Feeling nauseous, light-headed, or unusually tired.

Sources:

cdc.gov - heart attacks

Mayoclinic.org - daily asparin therapy (it has a section on aspirin during a heart attack)

Lithium batteries are happiest between 20 and 80% state of charge. You should not store them outside of that range. Charging a little often also doesn't hurt your battery like many seem to believe.

Charging while cold is bad, but storing in cold is good.

Also, NiMh and NiCd batteries are different tha Lithium based ones. Check what type of battery you have. Phones and EVs are almost always lithium though.
