We've heard that taking an aspirin a day can lower your risk of heart disease.
But now doctors say it can also help women keep their minds sharp as they get older.
That's according to researcher in Sweden, who studied women between the ages of 70 and 92 for five years.
Doctors found that women who took aspirin each day did better on memory tests over time compared to those who didn't take aspirin.
Researchers say aspirin can improve blood flow to your brain, and that's probably why it helps your memory.
