Oranges, like all fruits, go through a natural ripening process, which can take anywhere from a few days to a few weeks. During this time, they'll become sweeter, softer, and more prone to mold and decay. It's like they're going through a midlife crisis - they're trying to find themselves, but really, they're just getting old and messy.
As oranges age, they'll start to develop brown spots, become less firm, and eventually, they'll wilt away like a sad, forgotten balloon. But don't worry, this doesn't mean they're toxic or anything - they're just past their prime. You can still use them for juice, marmalade, or even as a face mask (just kidding, don't do that).

On a more serious note, some oranges are more prone to spoilage than others. For example, valencia oranges are more resistant to mold and decay, while navel oranges are more susceptible. So, if you're planning to buy oranges in bulk, make sure to choose the right variety, or you'll end up with a batch of rotten oranges that are only good for composting.
