Bananas are tempermental fruits. They break easily, bruise easily, and rot easily. They seem to spend a lot of time being green before turning brown.
The yellow stage is often a "don't blink or you'll miss it" situation. However, it's possible to prevent bananas from becoming overripe too quickly.
It all depends on where you store them, and more importantly, where you shouldn't store them.
Banana hangers help prevent the fruit from bruising and accidentally breaking. It also comes with another important perk
Bananas do not belong in the communal fruit bowl since other fruits release ethylene gas as they ripen.
This makes the fruits ripen even faster. The worst offenders include apples, tomatoes, peaches, avocados, and figs.
