Hey, that small invertebrate you found by the sea?

Please leave it alone.

Went snorkeling with a guide a long time ago in some coral reefs. 

When we saw a shark, the guide was like "Nah, don't worry. They're chill." Then we saw a tiny purple jellyfish, and the guide was like "WHATEVER YOU DO, stay away from this thing, it'll paralyze you and then you'll drown."

Moving water.

It's freaking dangerous. Water is heavy so when it's moving it has a lot of energy. It might not feel too bad walking through knee deep flowing water but if you fall the water will have more area to push on. You may not be able to get yourself on your feet again.

Manipulations by chiropractors.
And if the manipulation doesn't kill you, it can certainly cause paraplegia or quadriplegia, vertebral dissections.
The sad part is that chiropractors will never own up to the fact and they'll actually claim that patients are coming in with an active stroke. Unfortunately a lot of their research is skewed. I would highly recommend looking into the American medical association, particularly neurologist to see the detrimental effects that a chiropractor can have. It's unfortunate how many people die secondary to a chiropractic manipulations - particularly in the neck and back.

For reference, I am a occupational therapist who has seen plenty of paraplegics and quadriplegics secondary to chiropractic injury.

So I was trying to look up a DIY mixture to remove mold/mildew recently. A surprising number of sources (including an AI tool) suggested mixing bleach and vinegar.

Rule of thumb. Never mix anything for cleaning, there are far too many chemical weapons that can accidentally be made.

The Great Lakes. Just this past weekend 4 people decided to go in the water near my house even though the beach was under red flag warning and high waves. 3 got pulled out by a Good Samaritan when they got in trouble. Three days later and coast guard and fire department still hasn’t found the body of the 4th one. Rip tides are real. Weather kicks up fast. The Great Lakes are huge and dangerous. This is not your local pontoon lake.

Horses

we've lived with them for so long that unless you spend regular time around them, you don't know just how unbelievably dangerous they are. It's a good thing they're so stupid or we'd be f****d.

Movies have people believing they're these docile creatures that live to serve humans. Those are the ones that have been trained *extensively*. They are otherwise 1500 pounds of dumb panicky hair-trigger muscle.

Capacitors. Maybe most people don't interact with them, but for those that do (DIY electronics repairs), a typical PSU in a home computer have capacitors that can kill you. Shocking, I know.

Maternal hemorrhage. I am routinely shocked by expectant mothers who want to give birth at home, arguing that they can always transfer to the hospital "if there's a problem." No, no they can't. If the wrong type of bleeding begins, they'll be dead before the ambulance gets there.

Edit: as noted below, in some countries, certified nurse midwives attend home births with medications they can use to treat hemorrhage. However that is NOT the case in the US, where insurance requirements mean that most CNMs must be attached to hospitals. In many American states, "midwife" is not a restricted term, so self-described midwives with no qualifications at all get hired to attend home births. The results are a fairly predictable higher mortality rate for home births vs. hospital births in America.

Cat bites. Their teeth are very thin like needles, and oftentimes after a deep puncture, the top layer of skin closes leaving infection trapped inside from all the bacteria in their mouths. If you ever get bitten by a cat, go to urgent care asap for antibiotics. Even if it seems fine at first. Waiting even just a few days can lead to sepsis (blood infection) which can be deadly.

I work in veterinary medicine, and one of my coworkers almost lost her hand from a cat bite infection.

Inhaling too much helium.

I worked at a party store and we had someone rent a helium tank. We rented them by the week and then every week after there was a charge done to your card immediately. After 3 months we got a call from the renter's daughter asking if we could please stop charging her father's card. He had used the helium tank commit [self-harm] the day he rented the tank and we had charged him over $1,500 in the 3 months since.

It became a huge thing where we had to actively tell people once you fill your lungs completely with helium that the avioli can no longer process oxygen correctly. So while it's all fun and games to have that squeaky voice one super deep breath can end your life.

My friend’s father got into a verbal altercation with someone. They pushed him. He fell and hit his head on the pavement. Lights went out immediately and he was brain dead. They had to take him off life support not even 12 hours later. So sad every time I think about it. He was a good man.

Rust. If you run into a hole in the ground with rusty stuff inside, that does not get good ventilation. Dont go in. Rust is iron combined with oxygen. And it can eat all of the oxygen in the air. And fun fact, your body cant tell how much oxygen is in the air, but does sense carbon dioxide is there. So you dont know you are going until you are dead.

Hi I’m in EMS.

Please wash your hands before you eat stuff, so many people come in contact with so many other people who have illnesses that can be contracted by eating with unclean fingers. Even if you’ve been around people you know all day you never know who they’ve been around, and sometimes it’s not even illnesses rather random germs AND I KNOW THIS IS OBVIOUS TO SOME PEOPLE but next time you see a local EMS crew eating food with their funny colored gloves on it’s because we’ve made a habit even if we hadn’t run any calls that day.

Of course if you aren’t in healthcare you’re not being exposed to as much but sometimes you need a reminder just how dirty the outside world really is lmao.

Inhalents. I tried them once in high school. 2 weeks later a kid at another school died from using them THE FIRST TIME.

A couple weeks after that, I was offered them again. I told them f**k no and asked if they hadn't heard about the dead kid. They looked at me and seriously replied, "Oh yeah, it's okay. He used the wrong brand. He used the blue bottle, instead of the purple bottle.".

Hitting your head against a wall.

There's a pretty famous story about a basketball player who missed a shot, got annoyed and headbutted (if I remember correctly) the post the hoop is attached to.

Didn't kill him but paralysed him from the neck down for life.

People do die from doing this, I've seen people get mad and headbut something 100 times, but do it wrong once and that's it, you're dead.

Edit: He made the shot but was called out got a foul so it didn't count, he died 13 years later. Someone has replied with a video link but... watch at your own discression, its not nice.

I would venture to say most people realize what can kill you instantly but less commonly discussed would be dehydration. 


Yes you can die within seconds from it. 


Heart failure is what gets you and if you are already primed for a heart attack due to either unhealthy habits or genetics, dehydration can kill you in seconds. Some drop dead of a widow maker right there on the spot. 


Dehydration truly is a gamble so be cautious with it. Happens a lot in the summer months as people pick up alcohol and energy drinks instead of electrolytes. .

Anyone who works in a shop (hopefully) knows this… but compressed air. Not an uncommon thing for you to use it to blow metal shavings or other debris off your clothes after you’re done working, but if you have even a small cut somewhere and you get the air gun too close you can put an air bubble in your blood stream which will kill you the moment it passes through your heart. From what I’ve been told it is very painful and only takes a few seconds.
