How long do fuses last?

Could you elaborate on the longevity of fuses? Are there any factors that determine how long they can last before needing replacement? Is there a standard lifespan for different types of fuses, or does it vary widely? Is there a way to tell if a fuse is approaching the end of its life, or does it simply fail suddenly? Understanding the lifespan of fuses is crucial for maintaining electrical safety and preventing potential hazards, so I'm eager to gain more insight into this topic.
