　　Independent Writing:

　　It is as important for older people to study or learn new things as it is for younger people.

　　As people age, they tend to become more and more set in their ways. When we are young it is easy to revise our beliefs and adopt new perspectives, but over time, our thinking slowly becomes rigid. But just because this phenomenon is the norm doesn't mean that it's ideal. There are some advantages to more rigid thinking, but I think it's a good idea for old people to continue acquiring new knowledge.
