ELI5: Why is the life expectancy of foxes so short?

It baffles me its only 3-6 years.

Essentially nature is a cruel bastard, and life is hard. In the wild foxes (and other canines) are subject to many diseases, parasites, and competition from other predators cutting their lives shorter than their potential maximum. In captivity foxes live roughly as long as their domestic counterparts, with access to healthcare, food and water.
