I'm volunteer to donate because of I accidentally die, rather that it deserve someone who would have more luck than me rather than no one.
Now in Belgium it works a bit differently. Everyone is, by default, considered as a donor.
You can then register to either refuse it or to impose it whatever your family says.
This is because the law is that the doctors must always ask the family if they are ok to give organs from diseased family member even with the "by default donor", with the registration you can say "don't ask my family and just do it".
This can be used in two situation in my opinion, the first one being family that have different conviction and may refuse despite the opinion of the diseased. The second situation (mine) being not wanting to worry grieving family with one more difficult decision to take.
I purchase mostly digital books because I use to read at night next to my sleeping partner and e-reader is the easiest way for me. Also O don't have a very big house to store all.
Now from a piracy vs purchase point of view:
I actually buy ebooks as a mark of support to authors I like very much. Now I must confess that for some very popular authors, I trend to think that one book pirated or one book bought won't change a lot for them. So I buy mostly less known or indie authors at the end.
For notes I'm using Joplin with sync with desktop client through a nextcloud instance. Really a very nice app if you want sync with multiple devices anc user friendly interface.
For maps OsmAnd, I even pay a subscription to support the project (and have hourly updated maps which is pretty cool when I fix wood paths in openstreetmap).
I use helium314/openboard on day to day basis, but the few times I use termux or have to ssh a linux box from my phone, unexpected keyboard is really awesome.
A good one IMHO is Omnivore.
