Extravagant but worthless gifts help a guy get the girl

If men thought they were frittering away money wining and dining a girl to win her hand, they should think again.

Reporting in the journal Proceedings of the Royal Society of London B they analysed the function of a courtship gift and what the characteristics of a 'good' gift are.
They show that gifts can act as a signal of a man's intention. Offering an expensive gift may signal a long-term commitment but the man must be wary of being exploited by a gold-digger who intends to dump him once she gets the gift. full article
