It is well known by popular knowledge that men and women are different. Some authors has expressed this saying that men are from mars and women from other planet...or, is it the opposite? that those that are from other planet are we?; well I do not remember but the case is that if you want to know the 'scientific' reasons of such an assertion I recommend you have a look at this video where Mark Gungor, an marriage expert, explains at all detail the supposed reasons.
And you what do you think? Are we really that way?
