One of my co-workers had a stroke at work yesterday. It wasn't like she toppled over; she was just sort of drowsing off in her chair. Another co-worker became concerned and used a mnemonic we were taught at a recent CPR training (& which also goes around in emails): S-T-R (first three letters of "stroke") Smile (ask person to smile, check if face is drooping on one side) Talk (check for speaking trouble, word salad, etc) Raise (can they raise both arms?) The "smile" part pretty much confirmed the problem (face was drooping) and the other indicators did too, so they called 911. She's doing about as well as can be hoped today. So this STR thing and my alert co-worker might just have saved her life or prevented worse disability.
