STR: Recognizing the sign of a stroke

S *Ask the individual to SMILE.
T *Ask the person to TALK and SPEAK A SIMPLE SENTENCE (Coherently)
(i.e. It is sunny out today.)
R *Ask him or her to RAISE BOTH ARMS.

If you ever see someone fall and you're concerned they might have had a stroke, if they are unable to do any of these 3 simple actions, do not hesitate and call 911 immediately. Urgent medical action can make the impact of a stroke much much less. Thanks to Kitty for sending this information along!
