I use ones that are explicitly labelled with a black strip. My tactic for opening them is to put them between my lips and blow, which works pretty well but got really weird during the mandatory masking periods.
FWIW, our universal health coverage here will cover medical dental care, but not cosmetic. They'll patch up or remove your bad tooth, but I think it'd be harder to get an implant or a crown without paying for it. Weirdly, dentists are still one of the two or three basic services where people here are still willing to pay for uncovered medical attention, the others being eyecare and pediatrics.
When I needed surgery my private dentist still sent me over to the public system, though. Took a look at my X-rays, told me she wasn't gonna touch any of that without an MRI and an OR on standby and told me to go to my public doctor with a note and tell them to get me booked with a maxillofacial surgeon, which I did. It wasn't that big of a deal in the end, but the reaction was... revealing.
Absolutely, if you've ever made the types of sausages for cold cuts at home it's very obvious. People think the white powdery thing is just cool packaging (and to be fair in ultraprocessed crap it can be), but nope, that stuff is transparent when you get started.
Also, the "transparent stuff"? Disemboweled guts. I mean, the mold should be the least of your concerns if you're going by gross-out factor.
Wine is spoiled grapes, all cheese is just milk you left out for so long it got dry and sausages are what happens when you disembowel a pig and stuff its guts with its own minced ass. Today I ate a thing that looks like the first draft of an Aliens facehugger they rejected for being too spiky.
People buy food so processed they forget we're just gross hungry animals just putting random things in their mouths to see if it keeps them alive for a bit.
I keep telling people that the UI being similar is the least of the worries of a Windows expat. I promise all of Linux's mainstream GUIs are perfectly intuitive for a frequent Windows user. The things that are most annoying are software and hardware compatibility and not having to manually hunt for support or equivalent software.
I mean, in fairness their strategy for space exploration seems to be to point a starship in a random direction, hit "go" and beam down to every planet with a remotely breathable atmosphere in their PJ onesies.
The impressive part is they still seem to be the dominant superpower in half the galaxy, so... yay for them.
