An aspirin a day really can be good for your health according to a recent study from the University of Oxford researchers. 

In a study of over 14,000 volunteers, half were given a low-dose aspirin a day while the other half were given a placebo.  Twenty years later, the aspirin group exhibited 25% fewer cases of colon cancer and 35% fewer deaths. 

A low-dose aspirin is 81 milligrams and considered a baby aspirin.  The study indicated that no additional benefits were achieved with higher doses.
