The word that children say the most as they grow up is probably “why?”. Children always ask this and that, seeking knowledge as if they want to understand every object and everything happening around them. This is an extremely important developmental step that trains the most powerful weapon a human being possesses: the brain. Children can use their brain’s amazing information processing abilities to start building a massive knowledge tank, absorbing information like a sponge. Furthermore, they never ask a question just once but love to repeat the same question over and over, driving an adult crazy. This is not because the child wants to frustrate the adult. Just like how you cannot fully understand all of the meanings in a good book on the first read, a child learns through repetition and ruminating knowledge. If you do not repeat something, the knowledge only lasts in short term memory and is soon deleted, making it a very inefficient study process. Ergo, famous children’s educational programs such as Sesame Street and Blues Clues teach children things by constantly repeating the same thing. After that, the children watch the same episode over and over again to acquire knowledge.
As children do not know much about the world, they need to inherit knowledge from adults. Because adults possess a vast amount of knowledge, children need to ask a series of specific questions to build their knowledge base slowly and steadily. As their basic knowledge base builds, they can start to learn through other means such as books and encyclopaedias. However, whether you are a child or an adult, if you have something that you want to know, there is no faster and effective way of finding out than asking someone that knows. If you do not ask, you cannot learn and your brain will atrophy. Curiosity is a sign that there is still something you can learn. Thus, no matter how old you are, you should have the courage to ask a question. Curiosity is progress.
On the other hand, if someone (especially a child) asks you a question, do not brush them away; calmly answer their question and try to pass on as much of your knowledge to them as possible. That is your responsibility as a member of society; a sacred duty of feeding and nurturing the future generation.
