Women have boxed as long as the sport has existed but for years they were relegated out of national and international competitions in many countries around the world.

Here's a vehicle for the one percent. Dubbed as “the world's most luxurious RV” the 40-foot-long EleMMent Palazzo costs a staggering $3million USD – or more depending on the client's personal choices.
