Posted by GamesWithIsaacIts just hard to think about whats happens after death...
Hard to think about nothingness, indeed.
As your conciousness and what makes you is only your brain, if it dies, you do not exist anymore. Of course, we've got additional data stored in organs (not every single thing is stored into the brain, which's been proved from transplants) such as taste.
If your brain were to be stored somehow (frozen or whatever) and then implanted into a new living being, you would be able to live all over again.
Now, what about spirits? Do they exist? Can they interact with anything? Do they hold human form?
I don't think they would be able to control thier movement, and just drift away forever. But what would be the point? Also, gravity probably wouldn't affect them.
I would rather be safe in my brain than drifting in space forever.
