Have you noticed all the TV ads offering to help you get hooked up with the perfect spouse? They invite you to contact them in order to review your compatibility matches online. Here is the bait they dangle in front of you: "Aren't you curious about who you are compatible with?"
Here is the problem with those ads: People lie. They lie about their height, weight, age, and education. They lie about their temperament and character. They even lie about whether or not they are married. They call them MBA's…married, but available.
I suppose it's okay to use the matching services, but don't just trust, verify.
