Query: The Pocket Dictionary to Life:

I'd say you have to be familiar with Robert Heinlan before reading this. He's got some pretty strarnge ideas, that I can't say I neccessarily agreed with. Untill I read this book. It all makes sense now. I thought Lazarus Long was fairly annoying. Until I read this book. But seriously, if you are willing to go along with a couple of hundreds of pages of a old man giving you his take on life, you will see that with age comes wizdom. The plot here is secondary to the point, but its worth every scandalous and insestuous page.
