I don’t know enough, and I’m sure that there are drawbacks. But if something is clear is that planes cannot be commonplace, but just an exception. If they are replaced by airships, great, but if not, we need to just get used to not travelling this much.
There are exceptions, of course, but they should be that: exceptions. And the same goes for cars
Some time ago I read an article on hot water bottles as personal heating/cooling systems, and it’s great:

Since the I bought one, and in hot weather I store it in the freezer / refrigerator (for those that have one)
Also, water cools when it evaporates, so a spray bottle and a hand or electric fan is an amazing combo: spray your face and the fan multiplies the effect.
Right now I’m using Markor on my phone and any text editor on my computer (Zettlr mostly). For syncronization, I recently started using Syncthing, and having a separate app for that is pretty great.

Toilets in the USA have a ridiculously hight water level, most of the bowl is filled with water. Thus, for example, the typical scene of bullies dunking a nerd upside down in the toilet. Here in Spain they would, at best, get a bit of water on his head, while there they are saking his whole head.
The “ball soaking” was a reference to a reddit thread about a man with huge ball that had to hold them not to soak them in the water. In a european toilet that’s basically impossible.
KeePassDX (Android) + Syncthing to keep the file synchronized between devices.
I don’t usually open the file on PC, but there are clients for all platforms
