Which is better CHILDHOOD, Adulthood or OLD age?

For me... adulthood is still the best point of my life. I have experienced childhood and there were so many donts. There were just things that children are not permitted to do or say. In adulthood, there is this freedom that I have which I will never trade with anything else in this world. I can earn myh own money and spend it the way I want. I have my family who give me so much joy. I can travel to places that I once dreamed of as a child... It's true I have problems, but isn't it that these problems make our lives more meaningful because in encountering them, we learn from our mistakes and that makes us better persons. I haven't experienced old age, but I don't think it will be as exciting as adulthood.
