100 years : wisdom from famous writers on every year of your life

A collection of different authors’ briefs descriptions on every age of a human's life, from 0, the birth up to 100 year-old. All are quite true facts and interesting to read on.

At first, the number 100 is not that special to me, until I realize that this year is the centennial celebrates the achievements of the national parks and also I borrowed a book about the national parks the other day along with this particular one.
