I have probably about a quarter of my end needs mapped out / met.
I had a living will put together many years ago since I am not confident my family would pull the plug on me as I have expressed. I misplaced it though, so I probably will be needing a new one of those.
I need to sit down with a lawyer and do a final will and testament. I keep putting it off but really it's something everyone should have if you have anything of substance to your name.
I've taken care of some of my funerary arrangements though. After we burried my uncle, since he was unmarried, I picked up the plot next to him just in case. So if something is to happen while I'm young at least we'd get to be burried next to someone we knew in life. I guess that was a bit of a foolish / emtional purchase, but you never know.
