Swede here. I’m a bit confused by the whole flouride thing in the US.
We don’t add flouride in the water. At least not in amounts needed to get better tooth health.
Almost everyone users toothpaste with fluoride. The concentration is 1000ppm in toothpaste for children (below 6 years of age) and 1450ppm in toothpaste for children (6 years and older) and grown-ups.
We also used to have mandatory sessions with the “fluoride lady” in school. We all had to bring our toothbrush to school and got to dip it in a fluoride solution (mouthwash I presume) and brush our teeth while the fluoride lady pointed at a large scale model of teeth and gums. All kids were a little bit afraid of the fluoride ladies. I’m not sure if it’s still mandatory today, but I think a lot of schools (1st to 3rd grade maybe?) still has this on the schedule once a year.
Sweden has got a history of focus on tooth health since we have cheap healthcare (was free 50 years ago. Times are harder now so we pay $10-$13 per night at a hospital. Life is so hard! 😉) and bad tooth health is the cause of a lot of other health issues. Which in the end would cost our state medical insurance a lot more than fixing tooth health.
For the one with waaaaat too much time on their hands, Sweden has done some pretty dark shit in the name of “for the greater good”. Google a documentary about the Vipeholm experiments if you want to know more about one of the reasons to how the world knows so much about tooth decay.
2 months ago I thought I’d start learning IPv6 and started watch some intro videos on YouTube.
Holy crap… It’s a beast and it just felt like if you don’t know what you’re doing you might lose all control over your network. Ok. So a device didn’t get a dhcp address? No problem… It creates it’s open IP address and starts talking and try to get out on internet on its own…
Normally that’s not a problem since your normal home router wouldn’t route 169.254.x.x… But it just seems like there’s A LOT to think about before activating IPv6 at home. I’ve got a Creality K1 Max… Fun thing: factory reset also creates a new MAC Address… So there’s no way in hell thay I just let her lose by activating IPv6.
Ps. Yes, I most likely panic because I haven’t figured out IPv6… But until I understand IPv6 there’s just going to be IPv4.
