Recession and underwear

According to Alan Greenspan, the first thing to show signs of recession is the sale of underwear. He says it goes down because people believe that torn underwear can be hidden. !! Trust Greenspan to come up with such whacky theories. There are people who even in the best of times think it too troublesome to go and shop for UW. And how is he going to prove it? UW is a cagey topic- like sex. People can never be trusted to tell the truth!
