Phrase from nearest book

Odd idea that I've seen first on Grig Gheorghiu's blog. Here are the rules:

• Grab the nearest book.
• Open it to page 56.
• Find the fifth sentence.
• Post the text of the sentence in your journal along with these instructions.
• Dont dig for your favorite book, the cool book, or the intellectual one: pick the CLOSEST.

For me, the nearest book was Practical Statistics by Russell Langley, giving this:

The average duration of numbness in these tests was 50% longer with Prilocaine than with Lignocaine, but the lack of any information about the degree of dispersion around these arithmetic means makes it impossible to assess the significance of the observed difference.

It may not be terribly poetic, but it is a quite profound idea in statistics.
