Yes. Usually when someone has a stroke, the first foremost signs that you can see we use F A S T. Which is F A S T. F stands for face, you can see either side of their face is drooping, maybe when they smile they're eyelid is - maybe they smile their nasolabial fold is drooping, their eyelid is drooping. That's one of the signs. Then A is their arms. When you ask them to lift up their arms, it actually drifts. Yeah, you ask them to hold for 10 seconds, it will actually drift one side. Yeah, and then speech, S is for speech. Speech when they're speaking is actually slurred speech, so you can actually tell that they are having slurred speech, compared to a normal speech. Like how now you're speaking is normal. So they will have slurred speech. Yeah, and then time is where you say time, you have to note down the time, what time you notice these symptoms. And then you need to call the emergency ambulance.
