For the first third of the book, I really enjoyed it. I liked being taken on the unexpected journey through the hundred-year-old man's life, and how he had met every important world leader and worked for them - it was unusual, interesting and humorous. I also liked how he was able to defeat unexpected bad guys and get help from other geriatrics along the way. 
 For the second third of the book, I was getting bored with how everything just happened to him in life, and how none of it was avoidable - killing yet another person. Getting imprisoned yet again. 
 I ended up skimming through the last third of the book, not particularly interested in what happened, just needing to finish the story - which remained unexpected and bizarre, to say the least. 
 I was glad to finally finish.
