I think it's a good thing to do. I mostly stay in the house and I don't want to go out anywhere or do more bureaucracy stuff than I have to. Sure, I'll die eventually and then it won't matter, but we all die eventually and I'm alive now and I want to lie on my bed and rot.
But yes, I agree with the sentiment of making oneself useful before or upon dying. I'm thinking about getting a will so I can give what little I have to charity upon dying (which is funny cos I just said I don't want to do bureaucracy shit, but I really don't want the money go to waste).
