Men are from Mars?

Do ya remember this popular book (no.1 best seller of the last decade) by John Gray in the 90s, offerin' some advises for improvin' husband-wife relationships by understandin' each other emotionally? If i didn't remember the title wrongly, it's somethin' like "Men r fr Mars, women are fr Venus". It asserts the notion tat men and women r somehow different just like aliens from different planets. Their brains are wired differently (i added tat myself)... haha. However, some psychologists and feminists claimed tat men and women are very similar, e.g. men and women can both be gd engineers, why not?

I don't really wanna comment on women. But as a man myself, i've some rights to comment on men or at least on myself.
- Men are quite emotional children-like sometimes, e.g. head over heels and floatin' on the cloud when someone they like kissed them.
- Men are usually more competitive than women, they care about winnin' a game or smthin' more than women.
- Men haf better senses of humor than women.
- Men are more willin' to give in to women. (lets not hurt the women we like!)
- Men are usually more active and energetic than women, e.g. sports.
- Men are quite romantic creatures, like givin' surprises to the women they like.
- Men can be quite noble, sacrificin' or doin' anythin' in silent just to make the women they like happy.
- Men won't mind on the appearances of the women they like, e.g. fat, short, not pretty, tiny, etc etc.

(Men can be sexy too huh? :P)
