Besides printing issues: If I were a user of these adapters I'd be fine with what you got - it's readable, and I wouldn't expect high definition on this.
Updated Ubuntu over three or four LTS versions in the course of an afternoon several weeks ago - no problems, updated smoothly as fuck, machine (15 years old laptop) is running fine.
There's an alternative missing in all these graphics: Feet not on the ground.
If your feet are on the ground for hours and hours your heart will be in trouble to pump the blood back up all the way. It's even worse with standing. So see to that your feet are not on the ground, rest your legs on some support under the table, sit cross legged (it's feasible even in office chairs) and take every pose that's not feet in the ground.
Look for Wohnungsgenossenschaft or Wohnungsbaugenossenschaft. They are relatively common in Germany and Austria; Vienna is an example where the majority of flats are owned by such cooperatives. In Hamburg roughly 14% of all flats in the city are being provided by cooperatives which has huge advantages for those who get to become members.
All sources I know are in German language so if you want to read further just go for these texts and translate them into your mother tongue. Maybe start with Wikipedia:
You got a point there, and there may be a lot of data to prove that point.
I am part of a housing cooperative ("Wohnungsgenossenschaft" in German), and these cooperatives are noticeably cheaper because they are owned by the members/renters and don't have to generate any profit, just enough excess money to build new homes. The principle is very convincing if you live in it and save loads of money every month. The cooperatives employees aren't overworking themselves, too.
Perspective can't be the answer.
