Different types of knowledge.

While knowledge gained from hands-on experience is worthwhile to rely on in our daily lives, I believe that book is a more reliable source of knowledge and information as they contain many people\'s diversified views. It is undeniable that the experience-based knowledge is more intuitive and accessible than the written type of knowledge, which leads it to become a major reference for people to consult. However, one\'s memory is so volatile that he or she is likely to forget lessons that he or she has learned from incidents as time passes by, meaning the knowledge itself is vulnerable. Moreover, it depends too much on individuals\' predisposition since every person interprets the same experience differently in accordance with his or her background. In contrast, it takes long time to write a book because an author should refine his or her thoughts in a sophisticated way by collecting more data that can back up the core idea of the book. Plus, people can look through many books as they want.
