More Women than Men Now Do This- No Answer To Impossible Trivia

This week on Lite Rock Impossible Trivia, weekdays at 7:20a.m., I'm giving you 4 tickets to the Ringling Bros. and Barnum & Bailey Circus coming to Boardwalk Hall April 19th-22nd. When you win, you also qualify for this week's grand prize, 4 VIP tickets... and you are the guest ringmaster for the circus!

This morning's question:  As of 2011, more women than men now do this.  What is it?

We didn't get the correct answer this morning, so I'll carry the question over to Wednesday morning!  Good luck from Lite Rock!
