Not in hotels anymore, but spent 15ish years there. People die in hotels all the time. Every hotel I’ve worked at has their stories, and the ones with indoor open atriums are the worst. Sometimes it’s just natural causes (I’ve had twice where someone had a heart attack in the middle of an event) but sometimes it’s drug overdoes or suicides.

Most grocery stores make about 7¢ profit for every $100.00 spent on the “middle” of the store.

Most profit comes from the perimeter departments.

Stop using Q-tips to clean wax out of your ears. All you are doing is packing it further in and clogging your ear canals until the wax turns to a rock against your eardrum. Highly recommend using Debrox or some sweet oil and then flushing with warm water instead!

I work in IT

Computers are magic boxes that sometimes do what I want them to do.

I can fix them but a lot of the times I don’t know why what I did worked.

Turn it off and back on again isn’t just a funny saying.

It’s not really a “professional secret” but more people should know; you can use the Inspector on any browser to change the text of anything on any website and have it look 100% genuine. Again not a secret but a lot of people don’t know about this. It’s noteworthy since a lot of people still will look for mismatched font or spacing or other tells that something has been photoshopped, but that is utterly meaningless. Can make screenshots that look exactly like a real post with 2 seconds of effort.

That language isn’t stationary!
I’m translator and for the last few years my native language (Ukrainian) changing a lot.
We are bringing some old words and rules back and, at the same time, creating new ones, which is awesome.
But, unfortunately, I’m hearing all the time about “truth is only in vocabulary” and “new words aren’t real” and sometimes it is really pissing me off.
Languages are changing all the time! It’s their nature.
Yes, there’s a set of main rules and words but even they are changing from time to time.
People creating new words all the time, some of them are disappearing with time, some staying for much longer and that’s okay.

I’m an archaeologist, we got a find, I googled what it could be, that’s what we wrote down… admittedly a specialist will confirm but there’s a lot that we don’t know but hey that’s why we have specialists.

The lighter the coffee roast, the more caffeine it has. The darker the roast, the less it has.


To elaborate a bit more, the reason dark roasts taste bitter is not because it has more caffeine, but because it’s burnt to shit and that’s just how ash-water tastes. Heat destroys caffeine, so darker roasts have the least caffeine of all.

That my semi-truck can’t stop as fast as their car.

I need a couple football fields to slow down from highway speed, and that’s in absolutely clear weather… Stop merging 13 feet in front of me & slamming on the brakes for an exit, just stay behind me and wait an extra 2 seconds so I don’t kill you and endanger everyone around us.

Side note. Don’t hang around too close to us either, even something as simple as one of our tires blowing up can kill/seriously injure you by itself or cause us to completely lose control of our rigs if it’s a steer tire.

Sorry for being dark, but people don’t realize quite how dangerous semi trucks can be.

Shocking someone (like an AED or “paddles”) doesn’t restart your heart, it stops it.


People often assume the heart stops and an AED fires it back up. The heart is contracting, but ineffectively (an arrhythmia, it’s basically lethally uncoordinated) and therefore not pumping any oxygenated blood to the body. Which equals death before too long. So the idea is to stop the heart so it’ll reset itself to a normal rhythm.

Many films will also show CPR, and the person comes back from unconsciousness. This DOES NOT happen. The only thing CPR does is keeps pressure on the heart to pump oxygenated blood to the rest of the body. CPR is not a treatment, it’s a temporary measure to keep the bodily organs oxygenated long enough to get the heart restarted via shock.
