Can you die from fainting?

Almost never, but...: Fainting, as it often happens when not quite enough blood flows to the brain, not due to a heart problem, leads to a quick awakening once the person is lying down for a minute or two. A primary care doctor can evaluate to see if it is just this or more. If one is really unlucky, such as fainting when he is sweeping leaves off his second story roof, he'll tumble off, land on the concrete, and die.
