主題：Why do children tend to be happier than adults?
Children are happier than teens and adults because they still have their innocence. They don't know yet about the sinful nature of this world. They are closest to God during this part of their life because they have an open, pure heart.
Innocence: 天真
Sinful: 罪惡的
