This is a good example, thanks for bringing it up.
As you say concepts dont arise and fall( because they dont even exist).
A apple, a knife , a table, a person: we look at them and yes we observe some changes. After a day or two the apples color becomes less attractive etc. the table seems to age slower than that but still over the years it loses the new look; people age even faster than the table usually.
But the texts say actual realities like the khandhas completely fall away very very quickly( see my earlier citation from SPK.)
So what is happening..
Well when we think about the apple we have a very vague and conceptual idea of what is seen tasted, touched and thought about. In fact what we term an apple is really biliions, trillions of kalapas. And each of these kalapas is arising for a short time and then falls away, but is replaced ,( provided there are the conditions) by new kalapas. It is this continuity which hides the radical impermanence that is truly occuring.
Everyone , buddhist or not, has some knowledge of impermanence. They know teacups break, cars get old, people age and die. But that is merely the outward sign of the much more severe impermance of the khandhas. And it Is only by understanding -dependent on study of the unique Dhamma taught by the Buddha- that the direct knowledge of impermanence can develop.
