To Live and Die: An Authors Take

What are your thoughts on the concept of living a very long life?

I write Paranormal Romance for a living and vampires are my specialty. Because of this, I tend to think about immortality more than anyone should. The idea of living an extremely long life, scares me. Beyond technological wonders and scientific discoveries, what else is there? War? Civil unrest? Cataclysmic events? Famine?
I know this shit sounds dreary, but it’s worth thinking about. Living a long life sounds cool and fun until they tell you, ‘guess what? The suns got about thirty days left’. Or, any and all fresh water sources have been compromised. Orrrrrr. Fucking hell, CORDYCEPS!!!! (They are real btw) I tumbled and fell headfirst down a rabbit hole and now I’m scared of something else. Thanks Last of Us! I thought that shit was FAKE!
Anyway, to answer simply, no, I don’t think I’d like to live for 200+ years. The world is too fucked up and Mother Nature is dying.
No thanks!
