I would have to amend "we all start with physical attraction" to "physical attractiveness is the first and easiest thing to notice about people". I don't think it's a deciding factor for as many people as we might think - I've been turned off of plenty of attractive women online and in real life (okay, more women online than in real life) because I got to know them a little better, or read their profiles, and either nothing else caught my interest, or they actively grated on me. (That's "grated", not "gyrated".)
In other words, you don't have to risk losing THAT much in the gamble if you take a little time to examine the odds better.

Dating is a gamble - we all start with the physical attraction. You need to spend time learning about a person's attitude and behavior as you go along........ The trick is to REALLY listen.
