So, from Sahir's Ramblings, here's a sample:
[...]To be honest, I don't think about my future too much. Not that I should, being thirteen, but everyone puts some thought into it at some point, be it a sophomore thinking about applying to college next year, or even a four year old girl playing doctor in the backyard.
The future is a funny thing to think about. I sometimes think, what if all of a sudden, we just cease to exist. We won't burn up, or disintegrate, or anything painful at all. We simply wouldn't exist. We would never have existed, and would never exist. Just as if there was no universe, no time, no space, nothing. Hell, there wouldn't even be nothing! Simply nothing would exist. And we wouldn't necessarily know when things stopped existing. For example, we could just keep on living in our imaginations. Though nothing would exist, we would believe it does, and live on forever, not knowing if anything is real. Even this blog you feel you are reading could all be in your head. I'm pretty sure some philosopher touched on this topic before, but I can't seem to recall his name.
Anyway, I hope you're sufficiently freaked out.
