English can help someone meet women in two ways. First, women are more attracted to intelligent men, and a second language suggests intelligence. Secondly, approximately one billion people in the world speak English as a first, second or foreign language, meaning English speakers are able to converse with more women.
The research into what women find attractive suggests that, from a biological standpoint, women are attracted to men who can provide for them and any offspring, and who are willing to engage in teaching, learning and nurturing. Learning a language helps someone meet both of these criteria. Practically speaking, in more modern times, women look for men with good earning potential, and learning a second language can increase an individual's job prospects.
