Why are humans so stupid? Why weren't we created with automatic genius? Or at the very least, our own how-to manual.

Can you imagine? A how-to use manual for each individual. Lord, the amount of wasted time saved.

I can openly admit I should come with a manual. And I am also someone who often doesn't understand manuals, so I thank designers for fool proofing some necessities for me. Though I'm not as bad as some.

Redditor u/SugarCookieBear wanted to know what things we use that were designed to bypass our basic abilities to be... idiots, by asking:

Engineers of Reddit, what's the most ridiculous idiot-proofing you've had to add in your never-ending quest to combat stupid people?

I'm intrigued to discover how and when designers and engineers realize that what they are crafting needs to come with extra detail, for the lame crowd. And by the crowd, I mean society as a whole. Let's face it, we need help.

Don't Drink Up

"Wife is a civil engineer. The one that came to mind for her was that she had to add to the specification of a construction contract that stated that workers would not drink the water that accumulated at the bottom of an excavation."

"Everyone knows that water is for Dasani. Can't have the workers dipping into their profit."

Between Bridges

"We had a pedestrian bridge next to a bridge for vehicles, separated by about a 3ft gap. The bridges were about 20ft high over the water. So many drunk pedestrians climbed over the rails and tried to jump between bridges and didn't make it that I was directed to design a safety net to hang between the two bridges."

The Plug-In

"I work in facilities maintenance. Someone put in a ticket for a malfunctioned computer on wheels and I found the power cord was frayed. Not my gear so all I can really do is set it aside and have the biomed techs fix it."

"I put a zip-tie through the holes in the prongs of the plug, put 2 nitrile glove on the plug, zip tied the gloves in place, and wrapped up the gloves with duct tape. I got a sheet of printer paper and wrote "inoperative. do not use. do not plug in" and taped it to the monitor."

"Couple hours later I get a ticket for another COW with frayed power cord sparking. It turned out to be the same cart and one of the nurses cut the end of the gloves off, cut the zip tie in the end of the plug, and plugged it in and it arced and tripped a breaker because of the frayed power cord."

Can't Resist!

Ok. Some of those items make me concerned for surviving life. Who eats glass? I've seen some things in the world, but that would definitely be a first and hopefully last. I shudder to continue.

Roadblocks...

"Civil engineer here. While laying asphalt usually we close the road and cover using barricade tapes. But no matter his hard we try people always find ways to go through and ruin the whole process. Ultimately we had to use security to block the roads."

Don't go THERE!!!

"Chemical engineer. Please do not poop in the test room. I wish I was joking, but it happened!"

- encoding314

"My cousin is a chemical engineer. For weeks they had contaminants in their product. I forget exactly what fixes they tried, but they eventually found out via security cams that one of the night shift maintenance workers was peeing into one of the chemical vats."

- nota3lephant

LOUDER!

"I work on cars, so almost everything is designed around protecting people. My favorite is that we have to make the Hvac system louder and engine noise insulation worse because people will complain if they can't hear the systems running. We could make almost silent air ducts, but our warranty spend would go up."

- flyingcircusdog

Not a Hammer

"I'm a mech E intern, I walked in on my manager discussing a design with another engineer, all I heard was "so the guys will probably use that as a hammer so I made it out of this stronger material" "when they're working they will probably be throwing this small door open so I used stronger hinges and added a stop"

"It's things like this that I really appreciate about my internship, I likely wouldn't have thought about that myself."

On the 5th...

"A flat rail of a balcony is not a suitable substitute for it. And no, the insurance has not covered the total loss of the device after it felt from the 5th floor to the concrete pavement."

Y'all, does common sense no longer exist. Thankfully these people have the forethought to plan ahead. They are saving us, one idea at a time.

People Explain Which Lessons Aren't Taught In History Class But Should Be

It's highly believed that it is important to learn history as a means to improve our future.

What is often overlooked is that what is taught in history class is going to be very different depending on where you went to school.

And this isn't just internationally, even different regions of the United states will likely have very different lessons on American history.

This frequently results in our learning fascinating, heartbreaking and horrifying historical facts which our middle or high school history teachers neglected to teach us.

Redditor Acherontia_atropos91 was curious to learn things people either wished they had learned, or believe they should have learned, in their school history class, leading them to ask:

So apparently we are in the endemic phase of this nonsense.

We have light at the end of the tunnel.

So what now?

Where do we go from here?

Normal seems like an outdated word.

How do we get back to normal though?

Is it even possible?

What are reaching back to?

Life pre-Covid.

Those were the days.

If only we could bring them back.

Redditor hetravelingsong wanted to discuss our new normal in this hopeful "endemic" phase. So they asked:

"What’s something random you miss about pre-COVID times?"

What do you believe?

Is there a GOD in the sky?

Is he guiding us and helping us?

Life is really hard. Why is that is a big entity is up there loving us?

Atheists have taken a lot of heat for what feels like shunning GOD.

What if they've been right all along?

Maybe let's take a listen and see what they really think.

Redditor __Jacob______ wanted to hear from the people who don't really believe all that "God" stuff. They asked:

"Atheists, what do you believe in?"

The list of what irritates me is endless.

I mean... breathing too loud or dust can set me off.

I'm a bit unstable, yes.

But I'm not alone.

So let's discuss.

Redditor Aburntbagel6 wanted to hear about all the times many of us just couldn't control our disdain. They asked:

"What never fails to piss you off?"
