Thanks Orac. I think that explains the matter. Another thing that the writer said about the effect would be that a larger percentage of heavy elements would reduce the amount of hydrogen and helium, so that the burn would be slower due to that. So the star would be cooler and have a longer lifetime.

Further into the article the author suggested that there might be many more stars with planets in the life zone, and therefore much more life would develop, as the galaxies got more spread out. I think that was his major point. Even though the galaxies will be much more isolated in the far future there will be more planets capable of sustaining life for a very long time.
