A while back, and I am not sure how far back, I lost track of a banana. I had put it on a shelf intending to eat it later, but I forgot it. And then one day I found it. There it is below the nice yellow banana.
It had not rotted. It had dried out, probably because the building is kept with a remarkably low humidity.
No, I did not try it to see if it was still edible, and I do not think you should try this at home.
