Women are different from men, by a lot, in some key areas. For example, data show that women don’t: drown, compete as hard, get struck by lightning, use the Internet, edit Wikipedia, engage in delinquent behavior, or file patents as much as men do – and these are just some of the examples. Another way women are different from men? They have made significant economic gains and yet they are less happy now than they were 30 years ago. Source, Freakonomics
