People Break Down The Biggest Design Flaws In The Human Body

Okay, so here's the thing ...

How come humans only have one way to breathe but turtles are out here breathing with their lungs and through their butts?

I keep hearing that humans are the "advanced" species but try telling that to my constantly janky sinuses, postnasal drip, and hyper-responsive cough reflex.

I spend all spring nearly dying by drowning in my own boogers, but turtles can stay trapped under the ice in water for over 100 days cause they've figured out how to use their butt holes as a SCUBA system.

I don't feel very advanced.

Reddit user ZanzatheDivine96 asked:

"What are some big flaws when it comes to the design of the human body?"

Let's start with everyone else who was on board with my breathing complaints. Admittedly, nobody else brought up turtle butts, but my point remains a valid and shared one nonetheless.

"God I constantly choke while drinking water. It would be nice not having to worry about that happening so often."

- bubbledragonz

"We’re the only primates with a descended larynx. Most can breathe and drink water at the same time."

"A descended larynx let’s us produce a way broader set of sounds, which helped the development of complex speech. Very useful adaptation for the species as a whole."

"The trade off being that an individual chokes and dies now and then."

"This is not your normal hangover vomiting. No no. It involves violently vomiting."

"As if the stones themselves weren't bad enough."

"We actually have a little bit of webbing on our hands. Also you know when you have been swimming for a while and your fingers looks like raisins. The reason it does that is to get more traction underwater."

"Can’t turn off our ears like we can close our eyes. Sometimes I just want quiet in any situation!"

"That thin film of eyelid flesh is just enough to block almost everything out. We need a built-in feature that is similarly effective for blocking out sound."

"In our modern day and age I don’t typically have to listen for nocturnal predators hiding in the bushes."

- Emalan-R

"Oh my god, I never knew I wanted this until you've just mentioned it, now I want this so bad. The ability to shut off noise at will would be incredible."

"The eyes, specifically the retina is backwards."

"The 'support circuitry' is in front and the light sensors are in back. Hence the blind spot and tendency toward macular degeneration."

"Octopus eyes are done right."

"Eyes start as folds of double-layer cells and those cells divide and specialize."

"In at least humans, the layer that becomes the blood vessels and transmission nerves in the retina is on the inside and the layer that becomes the rods and cones is on the outside. So the light has to go through the blood vessels and such to be detected, and there's a blind spot where the transmission nerves gather together to become the optic nerve."

"In the octopus eye those layers are reversed, so the rods and cones (Not sure about cones, do octopi see in color?) are formed from the inside and the transmission nerves and blood vessels formed from the outside."

"Their eyes work pretty much the same as ours, except the layers were better arranged at the outset."

The Pee Manager

"This whole need to pee thing."

"Especially when I'm all cozy. That's some bull right there. I wanna speak to the manager."

- wyd55

"You ever get cozy at night in cool sheets on a warm summer night only to then have your body say 'f*ck that we pissin' so you begrudgingly go to the bathroom and as soon as you get ready to release your body's like 'sike we don't gotta pee no more I changed my mind we good now.' "

"Pisses me the f*ck off."

- 100BlackKids

Cold Sperm

"That sperm need to be slightly colder."

"Why did that evolve? Ever other cell is fine with being warmer but because of sperm being picky we gotta have nuts hanging out that can be kicked."

- Spirited-Ad-8061

"Yep. I would be happy to have my balls tucked away somewhere in my abdomen rather then swinging around, just asking to be bludgeoned."



"The brain being filled with feel good chemicals but refusing to release them."

- chuckyeagers

"The big sads - Chemical imbalances."

- Allieora

"Like your brain tries to kill you, but in the same time it tries to prevent it through the instinct of self-preservation."

- showMeYourCroissant

"In my case it releases all the chemicals all at once, causing me to be manic followed immediately by depression."

- Capraos

Asking Too Much

- daggersaber

So what's your biggest body gripe?

Don't act like you don't have one. Is it a knee? Elbow? Sciatic pain that feels like a stabbing charlie horse in your right butt cheek?

Is it the turtle breathing thing? It's the turtle breathing thing, isn't it?

We'll see you in the comments!

Children tend to believe just about anything they hear.

That there are monsters under your bed, watching too much TV will make your head explode, and silly faces will be permanent if you make them too often.

The sky is truly the limit when it comes to silly things that children will believe.

Some call it naivitée, other's youthful innocence.

But it's hard not to look back with embarrassment on certain things we believed as a child, that today might simply seem dumb.

Redditor Disastrous_Toe_6548 was curious to learn the multitude of silly things people believed when they were children, leading them to ask:

"What's the dumbest thing you believed as a kid?"
