I know you jest, but the more you think about it, the nastier a curse it is. For example, your crack would always be itchy. You'd never be able to put your clothes away because mold would devour them. And so on.
Don't bother with steps that are each different — making steps the wrong height/length is enough. If you ever walked up/down stairs that felt really weird it's probably because the builder ignored the international standards on that topic and built steps that are a couple centimeters off.
That was actually a thing in castle design. There'd be one step just high enough compared to the others that an assassin chasing the king would hopefully stumble on it, and the king could turn around and stab the assassin.
I'm sure you mean all the heights are a little different, but I'm envisioning where every step has to be taller than the previous one and the shenanery that would happen to make long stair cases navigable. Start with teeny tiny steps to end with uncomfortably large ones.
You must greet everyone you meet with a handshake and ten seconds of uninterrupted eye contact. Forced smiles and a serious talk about how you really are doing are also mandatory.
Pretty awkward if you ask me :)
Funnily enough, there are cases where that occurs. The Zed Mini is a great example, where the orientation of the cable affects it's ability to fully utilise USB bandwidth. I don't recall the reason off the top of my head, but I have shared stories with a number of people in the computer vision sector who have torn their hair out over those cameras only to discover that they don't work properly when the cable is "upside down"
Everyone is ever so slightly telepathic, functionally making a web of felt emotions with no thoughts connecting them so what you feel from this is basically a summary of the people in the area around you.
Example: Everyone could be focused at work, nothing major going on, until someone thinks about their significant other and all of a sudden there's a tiny bit of horny thrown in the mix, everyone knows its there, and no one knows who put it there.
Mirror every object. You don't realize how many things are designed with a right-handed assumption unless you aren't right handed. Also, most people can't read well anymore because it's all backwards
I used to tutor math at a company that insisted that we write upside down so the page was always facing the students. It really did only take like 3 days for it to feel natural.
Pretty sure it would kill everyone and ultimately destroy the universe or at least the universe's ability to sustain life.
After all, at some level, friction is the only thing that keeps you rooted onto the planet.
Sure there's gravity but there's that's only pulling you down, friction is what keeps you and the wind and the tree and the houses and everything else from sliding sideways as the Earth rotates underneath them.
The instant that rule went into effect, the Earth would become a 15,000 mph meat grinder under our feet.
Everyone's butt hole could be anywhere on their body. Everyone needs a different kind of toilet to properly position themselves. Everyone starts aligning themselves as friends based on the location of their butt hole. "Oh sorry I can't stay too long. My butthole is in my armpit."
Someone told me once that slapping something metal and grounded will discharge the energy and not hurt as much (you're expecting the impact of hitting it, so the electric shock comes with it; this is in contrast to gently brushing something and getting shocked unexpectedly). I've found it useful.
Welcome to Antarctica, friend! The buildings at Scott base are all fitted out with handrails that the occupants use to ground themselves periodically while walking around, because static buildup is such a serious issue down there.
It's impossible to determine the charge level of phone batteries. It's now up to you to keep track or your activities and estimate when you'll need to charge, otherwise it will just turn off on its own when the battery runs out.
Whenever you say anything to anyone the other person always knows exactly what your thinking is behind what you are saying.
That would make it nearly impossible to lie, cheat or deceive others, even for the smallest thing.
So that way when your girlfriend asks you if you would still love her if she were a worm, even though you would say, "Of course my love!" She would know you actually mean "what the fuck are you talking about?" And you would know she actually meant "my emotional batteries are running dry and I want you to recharge them"
At random times whenever you are traveling in any vehicle, you simultaneously feel a sneeze coming on, and yet have to pee a little bit too. However, you can neither sneeze nor pee until you are out of the vehicle.
Inconvenient on a bus/train or as a passenger, deadly if you're driving. Bicycles are right out, I suppose.
This'd likely a bit more than inconvenience, but honestly, to the degree that it would be more than that (or more accurately to the people to whom it would be more than that), I just don't give a shit.
Make it literally impossible to knowingly lie. Full stop.
Convenient because you can fly anywhere and through walls. People's commutes would be so much shorter! You could visit any country you wanted without even needing planes. Everyone would experience an unprecedented level of freedom.
Inconvenient because of the messy implications of getting stuck in walls if you turned it off at the wrong time. Also people would probably just be able to take anything they wanted without repurcussions so the world might devolve into chaos. You wouldn't really be able to jail anyone. Security and privacy would be hard to come by.
