Adding missing words/ removing extra words.

Please don't worry about minor text typos. These will almost certainly be caught during the editing process.

You may or may not classify these changes as minor. The earlier you kill kill bugs, the less it costs!

I appreciate the suggestions for wordings but I don't feel I want to make those preferential changes since the book has already been published and sold quite a few copies.
