Study reveals world's most jealous men

In relationships, it is well known than men are mostly jealous about sex, while women are mostly concerned about emotional attachments.

It reveals that Brazilian men are the most jealous; Swedish men and women are more concerned about sex than any other nation, and Japan is the least jealous country.
