Special... I'd say special is a way of saying someone is unique. By definition, and by virtue of DNA, of course we are all unique (well except identical twins, but then they're unique by being identical), so all special.

I actually think simply being alive is pretty special. I mean just think about it. Every single one of your ancestors, going all the way back through Homo sapiens, through to those that lived in trees, the sea, and even back to the "primordial soup" (or, if you're religious, dating back to whenever you believe creation happened) survived in order to create the next generation. The odds of that are incredible. Just think of all the famines, predators, natural disasters etc that every single one of your ancestors survived (until they'd reproduced anyway). There's probably a higher chance of someone winning the lottery, than of that particular person existing! So it's special in that sense...

Sorry if this got slightly off topic, you can probably tell I'm into the sciences :-)
