One in 10 had "silent strokes" - U.S. group study

At last an explanation.

"Routine brain scans in a group of middle-aged people showed that 10 percent of them had suffered a stroke without knowing it, raising their risk for further strokes and memory loss, U.S. researchers said on Thursday."

And they all went into the business of giving weight loss advice.

Now we know why Oprah, Mehmet and David are so damned stupid - silent strokes.

Too bad they are still IMHO dangerous.
