Details
Quoted from the source: ``From a very young age, shoes
for boys tend to be wider than shoes for girls. Is this
because boys have wider feet, or because it is assumed
that girls, even in elementary school, are willing to
sacrifice comfort for fashion? To assess the former, a
statistician measures kids' feet.''
