Should I take a daily Aspirin to ward off heart attacks and strokes?

But recent studies suggest that unless you've already had a heart attack or a stroke, this may not be the best idea. Family physician Dr. Mike Kolber, who also teaches at the University of Alberta, joins Dr. Brian Goldman to give you the dose on who might want to think twice about this age-old advice.
