What's the question
Book #1 is the best ..... IMHO
How many minutes should you take for lunch! Here's my theory on the question.
In the third book, "So Long and Thanks For All The Fish" the Guide mentions a
race that had three major questions in life. (or something to that affect)
1) Why do we eat?
2) How do we eat?
3) Where shall we have lunch? Add to that, that the Earth is the computer made to find the question.
And that IBM, one of the largest computer companies on the Earth, has decided
that the ultimate amount of time to spend on lunch is 42 minutes.
It seems to me that the 4th major question, or in better terms, the ultimate
question to life the universe and everything is, "How many minutes should we
take for lunch?"
