How long do fuses usually last?

I'm curious to know, how long can we typically expect fuses to last? Is there a standard lifespan for these devices, or does it vary depending on factors such as the type of fuse, the amount of current it's carrying, and the environmental conditions it's exposed to? Understanding the longevity of fuses is crucial for ensuring the safety and reliability of electrical systems, so I'm eager to gain more insight into this topic.
