Curmudgeons on the Court?

Is the Supreme Court just too darn old, by cracky?Eric Segall of Georgia State University thinks that some of the Court's members are, perhaps, a bit long in the tooth. And he blames the aging of the Court squarely upon the Constitution - upon Article III, to be precise, which provides that federal judges may serve during "good behavior" -- which effectively means for life.This one's a discussion for the ages.
