I think about this a lot, coming up to 80, as I am. I do keep ongoing decluttering, but still have stuff that I can't bring myself to get rid of. Mainly old letters, for example. Imagine! People writing in longhand. Puttng the paper in the envelope, writing on the address, and putting a stamp on it, then taking it to the post office. Then there's the memory of the excitement of seeing familiar writing on the envelope when you get it in your far clime. And sometimes to go back and reread some old favourites.
How can you get rid of that?
Still, the thoughts in the above video are somewhat interesting. The thing I don't like about it is that the voice, I'm pretty sure, is AI. Don't like this trend.
