The Solar System just got a little
older. New information from a
chondritic meteorite — a rocky
artefact from the Solar System’s
earliest days — puts the age of the
Solar System at about 4.5682 billion
years, between 0.3 million and 1.9 million
years older than previous estimates.

Unweaving the Rainbow, by Richard Dawkins
We are going to die, and that makes us the lucky ones. Most people are never going to die because they are never going to be born. The potential people who could have been here in my place but who will in fact never see the light of day outnumber the sand grains of Sahara. Certainly those unborn ghosts include greater poets than Keats, scientists greater than Newton. We know this because the set of possible people allowed by our DNA so massively outnumbers the set of actual people. In the teeth of these stupefying odds it is you and I, in our ordinariness, that are here.
