About 60 million Americans take an aspirin a day to reduce the risk of strokes and heart attacks. But for 10 to 30% of those who follow this recommendation, this preventive therapy turns out not to offer any protection.

German chemist Felix Hoffmann synthesized the first commercial form of the drug more than a hundred years ago to treat headaches, minor aches and pains, and fever—and we’re still discovering nuances about how the drug works, for whom, and for which diseases.
