"It seems that dim stars in the universe at large are like rabbits and bureaucrats: They may not be very bright, but there are a lot of them."Red dwarfs are the "forever stars," with lifetimes that currently exceed the known age of the universe. (However, unlike rabbits and bureaucrats, red dwarfs don't breed, and those that were born have yet to die.)
