Rescuing a drowning person can be just as dangerous as drowning. That drowning person is completely panicked and has only one goal: get air down air pipe, and a desperate drownee will do ANYTHING to obtain it: that includes climbing on top of a perfectly able swimmer and submerging them underwater to get their own head above water.
Immediately contact emergency services and throw something that floats at the drowning person. If you do feel confident to perform rescue AND the water conditions are favorable to your abilities, make sure you take something that floats with you so you can immediately hand it to the drowning person before they latch onto you. If they attempt to make a grab at you, immediately kick away (feet should be pointing towards to the victim), and thrust the flotation aid at them.
"People having seizures cannot swallow their tongue. Do not put anything in their mouth."
It's not that people actually swallow their tongue, it's that their tongue will rest in the back of their throats restricting their ability to breathe. People have heard this and misunderstood what was actually happening and spread misinformation for decades. So then things like this come out without actually addressing the truth or the root of the phrase. Your tongue isn't going to rip out of your mouth and go down your throat. It can rest in the back of your throat and choke you to death. That's what they are saying when they say "swallow your tongue."
