Study: 43 million Americans take aspirin daily - Reuters

An estimated 43 million U.S. adults take an aspirin every day or almost every day, according to a U.S. government survey, a figure that accounts for a fifth of the adult population.
Most are taking the pills for their health -- such as to prevent heart attacks or strokes -- the Agency for Healthcare Research and Quality found.
Aspirin relieves pain and reduces fever. But it also can lower the risk of heart attacks and strokes caused by blood clots, because it makes the blood clot less efficiently.
