We often feel this way, as if we have entered society in just a blink of an eye, and we have grown old in just a blink of an eye. In fact, I always disagree with the use of words such as a blink of an eye to describe time. If you blink again to see if your hair will turn gray immediately, even if you blink a few more times, you won't be able to. But when it comes to real use, this word is always more appropriate, because when your hair turns gray, it seems to be just a blink of an eye.
