Lol I've been asking myself that question all my life and I still have no idea at all.
Heh.. Not sure I've been asking it my whole life but I've been asking it a long time and I'm in a similar boat!
It's a tough philosophical question if you really try to get deep into it.
Glad to hear you have a great idea for this one, I look forward to seeing it!
And based on your previous entries and blog posts I have a feeling it will indeed spark some curiosity!
Cheers.
