why children are more impartient?

because they don't understand the things that have to be done to get things because they haven't had to do it themselves... patience is a learned behavior, not one present from birth. I've met a lot of grown people who are more impatient than children.

They have shorter attention spans than adults, and they are curious and want to learn, so will check out everything. They also are young and have tons of energy, because they rest when they are tired and eat better than we adults do as well.
