Due to lack of running water in those times (and still in many cottages) cooking is done above a fire, water is brought from the lake. A kitchen won't serve you well if you're just trying to get through a long winter of -30c.
Aren't those things organised the same way Apple face id is organised where the app itself can't get the biometric information, they just get a yes or no? That would be stupid as hell.
In Finland the government has allowed banks to offer (2fa) identification services to those that are using their services. If I sign into a government site using my banking ID, the bank gets paid for providing the service. To my understanding none of my actual ID information is transferred to a party wanting to identify me.
The Linkedin 'validate your identity' was the first time i was asked to actually take a picture of my passport/scan the chip. I'll refuse until they'll allow me to identify with my banking ID.
If you've got some money, get custom molded earplugs made for sleeping. Places selling hearing aids sell them. They spray some foam in your ear to take the print, and you get the custom plugs in the mail a few weeks later.
€140 is a lot for earplugs but it's amazing that they just slot into place in your ear, they're easy to pull out, and they're so small you don't feel them wether you're lying on them or wear headphones over them.
