In thinking about male and female attraction further, I may not be completely convinced by laws of science. Although I think humans have some sort of instinctual knowledge which attracts them to one another, there are also other things that simulate attraction.
One such example I mentioned in my article was alcohol but there are also things such as mood and setting that may perpetuate these feelings. For example when a girl goes out and dresses up she feels better about herself and that reflects to others. Moreover, you are more likely to find someone you are attracted to in a social setting as opposed to in the workplace.
So although there are matters of science involved in attraction there are also other things that influence it.
