Positive memories stay with us forever that we can always revisit with a smile.
Witnessing a loved one receiving their diploma after years of dedicated studying, celebrating a sports victory with other teammates, or traveling to a dream destination with your significant other after months–even years–of careful planning.
But in addition to reveling in nostalgia, there are other life experiences we'd like to soon forget but have a difficult time shaking off.
Curious to hear about some of the more ominous events experienced by strangers online, Redditor IM_Not_A_Robot_10110 asked:
"What have you witnessed that will haunt you forever?"

What happens inside hospitals are full of trauma and heartache, even medical professionals have a hard time processing what they encounter.
The Pediatric Patient
"X-ray tech here, but I was a student at the time. Called to ER for trauma code. Only know it's a pediatric patient. The terror as I walk around the corner and see it's a little boy, same size as my son. We go to take an x-ray and he's making this high pitched shrill wheezing noise. They couldn't intubate enroute so we were doing a chest/neck to see what was going on. His neck was full of air."
"Come to find out the story later, he had tripped and fallen in school and his neck went square on a desk and he had broken his trachea. Believe he was stabilized & flown out. Never found out what happened after."

Calling Time Of Death
"ER nurse. This won’t haunt me in a bad way, but it’ll stick with me for sure. We were coding a middle aged lady we knew was going to die. We were pulling out the last ditch stuff hoping we’d get lucky, but everyone knew which way it was going."
"Family was there and in the room. When it was clear we had run through all the Hail Marys and it was time to call it, the husband spoke up for the first time. He had apparently been an EMT for a long time so he knew what he was looking at. He said he was going to do the final round of compressions."
"It was very respectfully done. He got up to do his 2 minutes, the nurses quietly started turning things off so there wouldn’t be continuous alarms, we called for a pulse check which the husband did, then we called time of death. He was thankful we let him do that and I was thankful to be a part of it."

Missing Jaw
"Not me, but my roommates fiancé is a flight nurse. She told me this story around Easter."
"They showed up to a scene being told beforehand that there was a patient with a gun shot wound and bleeding bad but that’s all they were told. When they got there they found a woman who was sitting on the ambulance gurney completely lucid and looking around, completely missing her lower jaw. She said you could see down her throat and she looked like a zombie. Her lower jaw was hanging to the side by some tissue and when she looked about it swung around and dangled. She said the woman seemed relatively calm and when she tried to speak what was left of her tongue kinda moved but nothing but gurgles came out."
"It was not a suicide, her boyfriend accidentally discharged his firearm while they were in his car."
"She survived."

AIDS Epidemic Era
"Retired RN. I was working in the PACU and helped another nurse take her patient to his room. As I was adjusting something by his head, he grabbed my hand and started crying. He kept saying I don’t want to die. He was barely 20. In an isolation room. I looked into his eyes and tried to comfort him as he sobbed. This was in the early days of the 'AIDS epidemic.' He died within a week. To this day I still see his eyes and hear him sobbing."

Traffic accidents can be some of the most gruesome scenes no one should ever have to witness.
Accident Victim
"I live next to a busy street, inbetween lanes is a tram station. Teenager wanted to cross and got run over by a tram. Well, partly run over, he ended up with his body squeezed in between the tram and the tram station wall, with his legs stuck under the tram. It took about 1,5 hours until they had the equipment to lift the tram to get him out of there. They managed to reanimate what was left of him but he died in the hospital."

Dangerous Road
"It was Easter Sunday about 5 in the afternoon. I was driving home from the lake with a friend of mine on a country highway that’s pretty well traveled. It’s one of those single lane coming and single lane going where the speed limit is 70 roads. The intersections are far and few between so instead of an overpass it’s just a blinking yellow caution light. In what literally felt like the blink of an eye the car driving in front of me is struck on the drivers side door."
"The impact pushes both cars off to the road and onto the shoulder. I hit my brakes and was able to stop to help render aid. My friend and I get out of the car and run over to help. The drivers side door is crushed inward, driver has been pushed into the passenger side. It was a younger lady, maybe mid 30s. The impact pushed her out of her seat and into her daughter."
"You ever see movies where a dead body jump scares someone and it just stares at the with wide eyes and mouth agape….. yeah. The girl is ok but very confused. She has no visible injuries and is freely looking around so we unbuckled her and pulled her out of the car so she didn’t realize her mom was laying on her. As we do it I look at the mom and I can see a little life is left in her, so I said the only thing we could say. 'She’s alright.'”
"You could see the light in her eyes fade and she passes away. More cars stop and help out. As more people are here to help I start to realize that someone has been screaming, at me. In the back seat is her son. He must have been knocked unconscious and he’s now yelling, not out in pain but asking 'Is mom okay, is she okay?' I had no words for him, he was maybe 6. His sister was about 9. Thankfully about 4 of the cars that stopped were off duty first responders so they quickly took over for me. This was about 20 years ago, I was 17 at the time and I just saw a mom die in front of her 2 kids. I’m crying now thinking back on it and to this day I still refuse to ever take that road again."
"They finally build an actual stop light a couple years back. The area isn’t more crowded so I can only imagine what the motivation to improve that intersection was."

Pedestrians
"I was designated driver at my friend's 30th birthday party. Had just dropped off my last friend and I was heading home. Little blue car zipped by me going maybe 10 over. Maybe a block ahead of me I see the speeding car hit two 20 yr olds who were running across the street. They were running to McDonald's across from the nightclub they were partying at and didn't wait for a red light. I'll never forget the girls blond hair in the bright headlights as she got hit. One thing that isn't ever correct in tv shows when people get hit by cars is how much damage it does to a human body. I distinctly remember his legs laying like 2m from his body. Both died right when paramedics got there."
– SuchAGeoNerd
PTSD
"Getting hit by a car really is ugly. My girlfriend accidentally stepped on the street while we were having a minor disagreement and bam she was gone in a moment. I have ptsd, I can still see all the blood, her trying to breathe and the moment she gave up."
– More-Masterpiece-561
You never know when a friend or acquaintance is going through an extremely rough time–even though they present themselves differently in public.
All we could ever be as fellow humans is to always be compassionate.
Prolonged Guilt
"I found my roommates body in our apartment when I was in college. He had suffocated himself with a helium tank and a plastic bag over his head. That fucked me up pretty good, especially because I knew he was struggling with his mental health. He was cutting himself too, he tried to hide it but I noticed. And I didn’t say a word, i didn’t offer a helping hand. I could have done something to help him, but I didn’t. That guilt is still there, 10 years down the line."
– Jon__Snuh
What The Taxi Driver Witnessed
"I was driving Taxi once and I picked up someone who said he thinks he just saw a dead body. Said someone had jumped from the top of the parking garage. There was already an ambulance and what not on the scene. I remember briefly thinking of my friend Willzo, but dismissed it, I didn’t even think he was depressed like that. I found it odd that I would even consider such a thing out of nowhere. But I dismissed the thought and went about my work night. Couple days later I got a call from a mutual friend. 'Hey buddy, did you hear about Will? He jumped off the parking garage a few days ago.'”

People Explain Which Things Someone Can Learn In Under One Minute That'll Change Their Life
As much as academic scholars are held in high esteem for their higher education, so should those who have learned and applied valuable knowledge simply just by living.
Those with street cred have just as much of an advantage at succeeding in life, thanks to specific experiences that can't be taught in a classroom.
Curious to hear examples of what those might entail, Redditor WiSe_genX asked:
"What can you learn in 1 minute that will be useful for the rest of your life?"
Class is now in session.
A diploma isn't a requirement for being able to apply these life-saving facts.
A List
"Maybe not useful 'the rest' but very much so when it is"
"How to spot a drowning victim"
"Edit:"
"The basic warning signs of skin cancer"
– BirdsLikeSka
Worth A Try
"CPR: Lay person flat on their back on a hard surface, place your hands one on top of the other with arms straight, compress chest down to hell to the beat of 'Stayin Alive,' don't be afraid to crack ribs."
"Edit: Oh, and remember that if someone needs CPR, they're dead. You are working on a corpse. If they don't survive, it's because most people can't wake the dead with their bare hands. Talk to someone if you have to, but don't beat yourself up over it."

– liyexa7217
Let It Fall
"Also hot things. I pull out some weighty dishes out of our 550°C furnace at work and every time before I pull them out I repeat over and over in my head 'Don't catch it if it falls. Don't catch it if it falls.' I also usually put my free hand in my back pocket or behind my back."

There is much value in the lessons shared here that can change your life or those of others.
Now that plenty of helpful information was shared here, the next time you're about to be swallowed by a riptide, swipe left!
We all pride ourselves in knowing random bits of trivia.
While "useless knowledge" is the common parlance for these little fun facts we, often randomly, know, that seems an unfair label.
After all, who knows when a subject comes up in conversation, and you might be the only one who can answer a group question.
All thanks to the fact that you know a random piece of knowledge almost no one else on Earth seems to know.
Redditor Just_Free_Tea7 was curious to learn some of these obscure pieces of trivia, leading them to ask:
"What is a fact that you think barely anyone else knows?"
Don't be fooled by their cuteness
"The nuke stockpile in Washington State is guarded by trained dolphins that seek out and clamp a balloon on unfamiliar divers."- Gothsalts
A possible STD symptom no one mentions.
"Boanthropy is a psychological disorder in which a person believes they are a cow and try to live their life as one."

"Cool."- j451k4·
You mean, that wasn't flipper's real voice?

You always wonder what goes through their minds...
"Animals and other creatures each perceive time in different ways based on their Critical flicker frequency which is almost like their minds refresh rate."
"Dogs, for example, perceive time as being slower than humans do, and it's perceived as a little faster by cats."- TwilightArcade
Well that's disturbing...
"No one has found a centipede with exactly 100 legs, because all centipedes discovered have an odd number of pairs of legs."
"They have found centipedes with 98,49 pairs, and 102, 51 pairs, but never exactly 100."- ZagreusD
If you take a closer look...
"Raindrops don’t fall in the drip shape popularly conveyed. "

They'r contributions did not go unnoticed
"More pigeons have war medals than horses, dogs or mules."- Global-Program-437
It's easy to laugh off most of this information, as our lives might not be changed one way or the other for knowing it.
But we should always be open to learning something new.
And hey, if we ever find ourselves stuck with scratchy toilet paper, we can at least be grateful it isn't a corn cob.
The world is an ever changing place.
In addition to continuing advancements in technology, human behavior also continues to evolve.
As a result, what might have seemed "normal" 50 years ago might seem far-fetched today, while things which we today consider "normal" might never have even crossed the mind of anyone back then.
Making everything we consider "normal" among the many things in this world that continues to evolve at a rapid pace.
Redditor Primary_Berry_3560 was curious to hear what "normal" everyday things were anything but normal fifty years ago, leading them to ask:
"What is normal now but wasn’t normal 50 years ago (1972)?"
We could just leave whenever we wanted to!

“'Hello, is Johnny home?'”
"'Hi this is his mother, what do you want?'”
“'I was wooooondering if he could come out to play'.”
“'Well he’s doing homework right now but I’ll tell him you called'.”

It's amazing to see how much the world has changed in such a relatively short amount of time.
Leaving us to wonder what things will be "normal" 50 years from now, which today the very thought of would make us burst out laughing.
Don't mess with the ocean.
Why is that a hard rule for some?
It's like people can't help themselves.
Though it is vast and beautiful, the ocean takes life every day.
RedditorDankestKush420wanted to hear from the people who have survived the darkness of the sea.
They asked:
"Deep sea divers, what are your horror stories?"
I almost drowned from a small but wave on the Florida coast. So a deep dive is a lifelong HELL NO for me. But go ahead... tell us some stories.
Poof. Gone.
"I was watching a documentary about saturation divers the other day. Absolutely scary stuff. They live in a dome under the sea for several days/weeks so they don't have to decompress every day."
"There was this interview where one diver told a story about a colleague just vanishing. He was right behind him at one moment and then was gone in the next. No signs of an accident on the safety line, no sounds, no light signals, he was just gone."
PenguinSwordfighter
Implosions
"I used to work at a dive shop, a regular customer of mine told me on one of his deep cave dives at around 300 feet his main light imploded, and both of his backup flashlights failed. While this happened he also lost his guide line (read: life line back to the surface)."
"He was in a large room, so he dropped a reel with line on it and swam back and forth basically fishing for the guide line. He eventually hooked it and located it, but then had to make a decision which way to follow the line. The correct choice would lead him to safety, while the wrong choice would lead him deeper into the cave system. He made his choice and slowly followed the line out."
"He reached his first spare air tank that he staged and knew he chose the right direction. He had a long wait at each of his staged decompression tanks. It took him, from what I recall, around 7 hours to properly decompress and make it back out of the cave, all while not being able to see a damn thing."
pwnstar
side-by-side...
"I went on a group dive trip with someone who was pretty experienced, and he was telling us a bunch of stories about his wreck dive down to an old WWII-era Japanese warship sunken in the Pacific. One somewhat morbid but funny story was when his group went into the ship and saw several pairs of shoes strewn about, lying perfectly side-by-side."
"After they all surfaced later, one girl in the group was like, 'Why did they leave their shoes behind like that?' and everyone else just looked at each other like, 'Oh man... who's gonna tell her?' Anyway, the real horror story is about a father and son duo who had decided to go on this trip as a bonding experience. So the thing to note about WWII shipwrecks is that after over half a century, they're pretty much rusted to oblivion."
"One bad kick will effectively disintegrate a perfectly-preserved captain's log, just from the motion of the water. Well, the duo was exploring the inside of the ship, and suddenly someone hears a loud CLANG! The father and son had wandered into an enclosed room, and the door had slammed shut with both of them inside."
"At that point, the guy telling the story paused, and someone else in the group was like, 'Wait, so what happened to them?' And the guy was like, 'What the hell do you mean, man? They got trapped and f**king died!' And in that moment, I decided f**k that s**t - I am never, ever diving down to go check out the inside an old WWII warship lmao."

Unreal
"For as long as I been around the internet 1 diver story stuck with me. Not because of paranormal or unexplainable events. This person's story said they were deep diving with their father and literally saw a Lovecraftian size creature envelope his father ahead. After all was said and done at the surface he come to find out later his schizophrenia had come to while he was deep sea diving. I couldn't imagine seeing something your brain was telling you was real. Especially in that setting."

Vortex
"One time when I was on a diving boat with some friends, one of the guys on there told about a story about how he used to be an underwater welder, and one time he and some other guys witnessed someone getting sucked through a hole the size of a tic tac."

Why do people even go that far down?

"I’m by no means a deep sea diver, but I am a licensed diver, sea urchins are massive and everywhere, like you really don’t expect their size and how common they are."

Wrecked
"Did a 60M/200ft dive on a wreck in a shipping channel. The dive boat skipper should call up the harbour master and check if there are any ships scheduled, and if there are not good to dive. Anyway did the dive. 25 mins bottom time so a fair amount of deco."
"During the 12M deco stop we could hear the rumble of a very very very large engine. Hmmm. Kept getting louder. And louder. And louder. During the 9M stop it got REALLY loud we looked at each other, gave two thumbs down and bolted back down to 18M and just hung there figuratively shi**ing our drysuits until it got quieter after a few minutes."
"We then resumed our deco. A small pod of dolphins came in to have a gander at us which was cool. A big f**k off panamax sort-a-size ship had come within 100M of our deco buoy. Never dived off that boat again."
thedugong
Gruesome
Not sure if anyone has mentioned it, but the [Byford Dolphin Diving Bell Accident] (https://www.reddit.com/r/CatastrophicFailure/comments/4x1a2c/comment/d6blno6/) is pretty gruesome and scary. Basically, when deep see divers were returning to the surface, they were in a decompression chamber at a very high pressure."
"And there was a catastrophic failure of the decompression room that meant the air depressurized several atmospheres almost instantaneously and killed a couple divers by literally exploding them from the pressure release. Not sure what could be more of a gruesome tale than that."
anon_e_mous9669
The Worst
"Not my story but still wanted to share: it's the story of a diver who was hired to remove and bring back bodies from a bridge that collapsed into semi deep water with numerous cars on it. Some people made it out of their cars and some didn't. But the worst thing that he saw was the bodies of children still stuck in the cars while the parents saved their own lives. The thought of going into murky water to essentially fish up corpses that are like a day old chills me every time I think about it."
sarper97
Nope!
"I went diving to a wreck around 200ft down, and I heard this terrifying roar and saw some creature almost twice the size of a blue whale. Noped right outta there as soon as I saw that, I'm not going there again, I'll stay in my lifepod."
Overgrown_fetus1305
Well that is all I need to hear. I'll stay on dry land, thank you.
