Just a note on the idea that old stars could be expected to be home to old civilisations (and variations on that idea): The oldest stars are not necessarily good locations. Our solar system benefits from having being formed largely from the débris of previous generations of stars - this includes the heavy metals and interesting materials that civilisation (and our biology) rely on. These elements wouldn't be available to the systems of early-generation stars.
Additionally, the densely populated (in terms of stars) parts of the galaxy are also arguably very hazardous to life, since there's a) an awful lot of large objects crashing through the neighbourhood , and b) lots of not-necessarily-healthy radiation.
In other words, being out here doesn't necessarily place us in the boondocks. 8)
