Read 'em like a book... or an FBI agent

You're sitting at the poker table, your legs are bouncing slightly, you're rubbing your neck, and you're blinking at rate of 15 times per minute. What does your opponent know about your hand?  Phil Hellmuth's new book, Phil Hellmuth Presents Read 'Em and Reap: A Career FBI Agent's Guide to Decoding Poker Tells, co-written by Joe Navarro, will help explain it all.  Navarro is an ex-FBI agent who describes how to use interrogation techniques he learned on the job while playing cards.  My copy just shipped today, and I can't wait to dive into it.  I suspect these techniques will be useful in a variety of situations, including interviewing, negotiations, and buying cars :).
