MYTH: Your heart stops when you sneeze.
REALITY: When a person sneezes, he/she increase his/her intrathoracic pressure and can decrease venous blood flow back to the heart. The heart may compensate for this by a slight change in its beating rate, but the heart and its electrical activity should not stop during a sneeze.

MYTH: Using a cell phone in a hospital is dangerous.
REALITY: Despite the signs in most emergency waiting rooms, studies have found little to no significant cell phone interference with medical devices. In 2005 the Mayo Clinic ran 510 tests with 16 medical devices and six cell phones. The incidence of clinically important interference was a mere 1.2 percent. A 2007 study on cell phones "used in a normal way" found no interference during 300 tests in 75 treatment rooms.
