Type A people are just the opposite of Type O people. When they were young, they were resolute and strong everywhere. After entering the society, they began to restrain themselves and showed a steady and modest attitude as they grew older. They tended to become cautious people who did not want to overexpress themselves. However, generally in old age, they become more stubborn.
