Surviving will be a miserable ordeal. That being said, all of my ancestors have survived every major calamity in the history of life on earth. The way I see it, I owe it to them to try surviving whatever comes next. A few select generations lived through much, much worse.

It may sound bizarre, but I don’t believe in an afterlife so I might as well lean into something to give me inspiration. The idea that I exist because my extremely distant ancestors survived every mass extinction gives me a sense of wonder.
