First of all, children was deeply loved and protected by their parents. They do not need to worry about anything and can do whatever they want to. I think this is the most wonderful advantage of childhood. When a person grows up, he or she will never have this kind of advantage again, for an adult is supposed to have received enough education and know what he/she should do and what not. Thus, adults can only do everything they should do whether they like it or not. Moreover,the more they learn about the world, the more worries they will get.
Thus, many adults wish they would be children once more.
Secondly, children can learn much more than adults. When babies come to this world, they know nothing and have a great thirst for knowledge. It is much easier to educate them than to teach adults just like a piece of blank paper is much easier to be painted on. Furthermore, children learn by observing how people around them act and imitate them. While adults emphasize too much on the ways of learning, they do not learn in best ways in most cases.
Obviously, children have better memories than adults. This can also explain why children learn more things.
Thirdly, children are brought up under the great care of their parents. They eat all kinds of nutritious food, and they are taken out to do physical exercises regularly. Thus, they are very healthy. However, adults have their own opinions on food and only eat their favorite food. They do not take in all kinds of nutrients.
Also, adults are busy with their work.
When they go back home, they always feel very tired and are unwilling to do anything else except sleeping.
Thus, they have little time to do exercises. No wonder adults are not so healthy as children.
I will always remember the days of my childhood. How I wish I could be as carefree and curious as a child once again, and relive those happy days!
