Blood Clots/Stroke - Now They Have A Fourth Indicator
Remember the first three letters S T R
S — ask the person to Smile
T — Ask the person to Talk and speak a simple sentence
R — Ask him to Raise both arms.
If the person has trouble with any one of these tasks he may be having a blood clot or stroke. Immediately call 911.
Now the fourth sign — ask the person to stick out his tongue. If the tongue goes to one side or the other, he may be having a stroke.
