Conversation Chemistry is a 298 pages long guide that will teach you all you need to know about communicating with the opposite sex. It covers both verbal and non-verbal communication (such as body language and non-verbal flirting). The Conversation Chemistry guide is meant for all people - it doesn't matter if you're in a relationship or not, you have to know how to communicate with the opposite sex.
If you're single, you'll learn how to approach someone you like and talk to them in a relaxed and comfortable manner. The Conversation Chemistry will teach you how to always stay interesting, flirtatious and never run out of things to say. You'll learn that the look is really not that important - what you say, both in words and in body language, will make all the difference.
If you already have a partner, then the Conversation Chemistry guide can help you improve your relationship. The fact is that proper communication can prevent arguments, help you express your true feelings, and keep your relationship fresh and interesting.
Conversation Chemistry is gender specific (there's a version for women and a seperate version for men), so be careful that you order the right version.
