The Theme of 4,000 Days

I think the theme of this book is that "there is nothing more precious than a free life."
He didn't have any free while he was in the prison and he said that it was most harsh time in his life. He didn't have free and human right. He didn't have free to eat, speak, act, behave, and live. Everything was limited and being under surveillance. After he spent 12 years and became free, he couldn't feel free and still lacks free life. Because the limited life at there was so harsh that still takes free away from him. He knows that the free life is the best thing now.

So this book and the author, Warren Fellows, shows the "bad example" life for readers and says that "there is nothing more precious than a free life."

In his case, that was drug abuse. But person who commits criminal must to go to prison and being taken free away. Taking drug undermines your health and committing criminal can make other's life fall through. But at the last, everything go into you in hundred times worth.
