My take is that they don’t track you for fun. They track you to sell you shit. Most people buy what they see in ads and believe fake promotions so this is a good business model.
Best way to stay out is not to hide absolutely everything. It’s to block ads and don’t buy so much stuff. Obviously don’t give out data you don’t have to, block trackers, use privacy tools. But don’t feel bad if some data gets out. You will never block everything and a lot of it is not that important if you’re not playing the game.
Dental is tricky in many countries. It’s delicate, easy to go wrong and very often painful. In Poland I used to do simple things like fillings using public insurance and I’ve heard many times that I’m crazy and for sure they will fuck it up. I think it’s simply because it’s it expensive and will go wrong people will think it was inevitable. But if it’s free and goes wrong people will say it’s because it was free. So in my experience even if public insurance covers dental people tend to avoid it.
True story: some newspaper in Poland organize a competition for the weirdest name. The guy who won had last name of ‘Zyc or Cyc’ (in polish, of course). Basically when his grandfather was registering his name some guy couldn’t read it or something so he put ‘Zyc or Cyc’ and it stayed like this in the documents.
According to this guy when police would stop him and try to write a ticket they would get confused and ask him which one was it? He would say that maybe they shouldn’t write anything because their boss will they they’re stupid or something. They would usually let him go.
