By “free social media”, did you mean “no-cost” or “unhindered”? Because in my experience, at least 95% of people are completely incapable of judging their own online safety (especially in regard to the “no-cost” social media sites) just from their lack of technical background knowledge. I do not see why any of the stated groups should be exempt from that?

Yes. Heating (i.e. burning) beef to more than medium is now punishable by up to 2 years in prison. Asking people to commit a crime by ordering such a product can result in hefty fines up to 5000€.

Why not just test it from a bootable stick? My one one experience with a touchscreen was very positive (Plasma on Manjaro).

I’m from Germany, and none of the things you said are true. For example, to get from Aachen Central station to Hamburg Central station the cheapest option is 23,90€, but that connection is from 8pm to 3am. If you want to ride in the day, your cheapest price is the Quer-Durchs-Land-Ticket (“Cross-Country Ticket”) at 44€. But that way you are only allowed to use regional trains, which will make it a 7 hour train ride. If you want to use intercity trains (still a 5 hour ride), you will pay around 70-90€. And all of that is for 2nd class.

The age cutoff for children to travel for free is 6 years, children from 6-14 and 15-27 years travel at variously reduced prices (39€ for regional-only, 42€ for intercity).

I don’t know where you got your information, but here in Germany, we are in the same situation as the UK. And while trains in the UK may be painfully slow on cross-country travel, I have felt that they were much more comfortable to travel on, given the absolutely abysmal state of a lot of our trains.
