Do circuit breakers get weak?

When a circuit breaker trips repeatedly, it is usually because of a problem in the wiring, such as a short circuit or ground fault problem—or because the circuit is overloaded for the amperage rating it carries. But from time to time, a circuit breaker may simply wear out and get weak, or fail entirely.
