Funnies - Why woman walk behind men in Afghanistan?

I found this hilarious.........

"Why Do Women Live Longer?

Teresa Brown was interested in gender roles Sunni Muslims particularly in Afghanistan.  Back in the 1990s long before the current Afghan hostility she spotted that women walk about four paces behind their husbands.
When Teresa returned to Kabul in 2011 she noted with regret that women still walk behind their husbands.  She pondered why, despite the establishment of women's rights, wives still pace behind their husbands.
Later the intrepid reporter fell into conversation with one of the Afghani women and asked, 'Why are you so happy with an old custom that you once tried so desperately to change?'
The woman looked Ms Brown straight in the eyes, and without hesitation said, "Land mines."
She filed her report back to America with the leader:

Behind every Afghan man, there's a smart woman!"
