Why are pretzels so good?

Can you tell me, what makes pretzels such a popular snack? Is it their unique twisted shape, the salty taste, or perhaps the soft and chewy texture that melts in your mouth? Have they become a staple in our diets due to their versatility, allowing us to enjoy them as a snack, side dish, or even as a main course? Additionally, have pretzels' health benefits, such as being a good source of fiber and carbohydrates, contributed to their widespread appeal? Or is it simply because they remind us of our childhood and bring back fond memories? I'm curious to know what factors make pretzels so universally loved and adored.
