from a forward I recently read: RECOGNIZING A STROKE:

"RECOGNIZING A STROKE:

Thank God for the sense  to remember the "3" steps.

Read and Learn!

Sometimes symptoms of a stroke are difficult to identify. The lack of
awareness spells disaster. The stroke victim may suffer severe brain damage
when people nearby fail to recognize the symptoms of a  stroke.

Now doctors say a bystander can recognize a stroke by asking three simple
questions:

S  *Ask the individual to SMILE.
T    *Ask the person to TALK, - to SPEAK A SIMPLE SENTENCE. (Coherently)
        (i.e. . . It is sunny out today)

R   *Ask him or her to RAISE BOTH ARMS.

NOTE: Another 'sign'  of a stroke is this: Ask the person to 'stick' out
their tongue. If the tongue is 'crooked', if it goes to one side or the
other, that is also an indication of a stroke.

If he or she has trouble  with any one of these tasks, call 911
immediately and describe the symptoms to the dispatcher."

if this is not accurate
please let me know what needs to be changed and I will edit this entry
