" According to a 2004 study by Johns Hopkins, 10 percent of 20-somethings suffer from compromised hearing (compared to 8.9 percent five years earlier), with some experts blaming endless iPod and cell-phone use. Here, a few preventive strategies:  1. Try noise-cancellation headsets - or wear earphones over earbuds - when listening to music amid loud ambient sounds (e.g., lawn mowers).  2. Take earplugs to concerts and clubs. If you can&amp;#039;t hold a normal conversation, insert immediately. Ditto when riding on noisy boats or bikes. 3. Lose the cigarettes. Smoking has been linked to increased chances of hearing loss. "^^<http://www.w3.org/2001/XMLSchema#string>
