I'm definitely not happy about it.
Oblivion is inevitable, and I accept that, and have made what peace I can with it, but I'd be lying if I don't hope to somehow be able to cheat death in some capacity, regardless of the logical impossibility. It's just a very sad thought I mostly try not to dwell on. We live such short, limited lives, most barely aware of the astonishing beauty of the universe they're in, and it's tragic that even those of us that appreciate only have one short century at best with it before a most likely painful, terrifying cessation of existence.
In the meantime, I strive to live the best, most kind life I can, experience and cause as much happiness as possible, so at least I can know I did as much good in life as I could before it's stolen from me.
