Aging is a very natural thing to happen to anyone or anything, this is because everyone who has life will definitely feel the name aging and dying. This is no exception for fruit produced by plants, when a plant is experiencing a season of excessive nutrient absorption, the excess nutrients will be channeled into the fruit so that humans who consume the fruit will get nutrients from the trees.
Then every fruit produced by these plants will experience several periods, the initial period is youth where at this time the fruit tends to be hard and not too tasty to eat. Then the next phase is the ripe period where this is the best point of a fruit to eat. While the last is old age where the fruit will decay.
