Dementia is a terrifying disease. I remember reading "Flowers for Algernon" in middle school, and it struck me how similar the concepts are. The idea that you can be stripped of everything: everyone you know and love, everything you know and have come to appreciate. You don't even die, at least not immediately. You just live on as just another animal, living on whatever vague senses you have left.
Even if some religion was undoubtedly true, I'm still fucked. The fact that I know I'm going to die someday makes me who I am. Everyone has to spend life doing shit that they feel benefits them or people around them because it's embedded in human nature. But if i live forever, I can do that thing literally whenever. What's the fucking point? Everything you can do other than slave away, worshipping some narcissistic god, you eventually do. It's just as bad as a slow fucking death.
