I volunteered at both a hospice and a facility for elderly care when I was a kid. And I don't know. Each person was still different. Some spoke often of their kids, some of random places they'd been, the wars they lived through, and some were just all about what TV shows were big at the time. I don't think any of us really know how we'll be when the time comes.
Personally, I hope I don't care about whatever I did or did not accomplish at the end of my life, only that I lived and can find joy in that alone. It's amazing that life at all exists in the harsh universe, more amazing that it evolved into something as sophisticated as us, and then incredible that we formed societies with art and music and literature. To live at all is something exotically rare, perhaps even unique within the trillions of miles of empty space out there.
Anyways I smoked a joint I found earlier, it's been about a year, so yea. Maybe I am overthinking things.
