Love Lab: Do men lust and woman love?
Today our Love Lab looked at lust, as our eight volunteers met for the first time and we discovered whether there were any sparks created purely by physical attraction alone.
The volunteers - four men and four women - were then given a rundown of basic details about the others, including marital and financial status and backgrounds.
The results, as presenter Michael Mosley found out, showed marked differences between the sexes. The men were still guided primarily by appearance, while the women were swayed by factors such as perceived stability and success.

What do you think? Are men guided by sexual attraction over compatibility? Do women let their heads rule their hearts? And is it just men that lust first and ask questions later? Share your views.
