We've all heard that an aspirin a day can keep heart disease at bay. But lots of Americans seem to be taking it as a preventive measure, when many probably shouldn't.

In a recent national survey, more than half the adults who were middle age or older reported taking an aspirin regularly to prevent a heart attack or stroke.

It's springtime in Pittsburgh, and throughout the city, Callery pear trees are sprouting beautiful, white blossoms.

But that's just the problem. Simply put, these trees stink.

"This whole place smells like dead fish," says Sheila Titus. "I mean everywhere. Everywhere you see one of these trees with the white on them."
