Then I went to this amazing site (actually, not so amazing but it was an early hit on a Google search) that made this statement: "The pendulum must be suspended from a rigid support. During operation, any elasticity in the support will allow tiny imperceptible swaying motions of the support, which disturbs the clock's period, resulting in error." (Wikipedia: Pendulum, 6.22.2009)
So one moral of the story is: "If you're life is going to be lived as a pendulum, be sure your support is solid!" A second goes like this: "The closer the bob is to the rod the shorter the period of oscillation (the time it takes to travel the distance traveled between the extremes)."
