"Men think about sex every seven seconds"
Nope. More like an average of every 158 seconds.
"Nice guys finish last"
It depends. Over the long run, being a nice guy can lead to happiness, success and good relationships. On the other hand, they aren't as likely to end up in prestigious positions or to be chosen as leaders when times are tough. Rude people have higher credit scores and jerks make more money. And it can be hell on your love life: young women and women who most enjoy sex prefer bad boys.
