Stroke

Stroke was the second most common cause of death worldwide in 2004, resulting in 5.7 million deaths (~10% of the total). Approximately 9 million people had a stroke in 2008 and 30 million people have previously had a stroke and are still alive. It is ranked after heart disease and before cancer. Geographic disparities in stroke incidence have been observed, including the existence of a "stroke belt" in the southeastern United States, but causes of these disparities have not been explained.

Famous quotes containing the word stroke:

    Manners are the happy way of doing things; each once a stroke of genius or of love—now repeated and hardened into usage. They form at last a rich varnish, with which the routine of life is washed, and its details adorned. If they are superficial, so are the dewdrops which give such depth to the morning meadows.
    Ralph Waldo Emerson (1803–1882)

    He will not idly dance at his work who has wood to cut and cord before nightfall in the short days of winter; but every stroke will be husbanded, and ring soberly through the wood; and so will the strokes of that scholar’s pen, which at evening record the story of the day, ring soberly, yet cheerily, on the ear of the reader, long after the echoes of his axe have died away.
    Henry David Thoreau (1817–1862)

    one gratuitous flourish—a stroke of white or
    a run on the clarinet above the
    bass tones of the orchestra ...
