It's ceasing to exist, in my opinion. And it scares me shitless, the prospect of not being for the rest of eternity, even if i won't notice.
It also drives me to want to live as long as possible and see us much as possible. A huge number of people don't get the chance to live the way we do, they struggle simply to survive.
I feel privileged to have the choice to live in whatever way i wish, and want to make the most of it.
