Adulthood

1. The age for becoming an adult is 18 (technically 21 due to drinking) because at that age you are ready for college and that is the sign for adulthood. They are free to make their own reasonable choices.
2. An adult is someone who is responsible for their own life and can do whatever he wants. They like to make reasonable choices but they can go crazy sometimes. They not only have to help themselves but they need to help others in need.
3. People don’t get useless at all because their family still values them and loves them. They could be useless if they don’t have family and are the age of 98. They die and people don’t really care.
