A journalist had done a story on gender roles in 
Kuwait several years before the Gulf War, and she noted 
then that women customarily walked about 10 feet behind 
their husbands.
 
She returned to Kuwait recently and observed that the 
men now walked several yards behind their wives.
 
She approached one of the women for an explanation.
 
"This is marvelous," said the journalist.  "What 
enabled women here to achieve this reversal of roles?"
 
"Land mines," responded the woman.
