Final answer:
It is false that there are no signs to identify potential victims of autoerotic asphyxia; warning signs might be present but not always easily recognizable. Contrary to common myths, drowning is often a silent event where victims cannot shout or wave for help.
Step-by-step explanation:
It is false that there are no warnings or visual signs to identify potential victims of autoerotic asphyxia. Warning signs and visual cues can sometimes be present in an individual's behavior or circumstances. However, predicting and identifying risk with certainty can be very difficult. People participating in autoerotic asphyxia might inadvertently put themselves at risk of losing consciousness or even fatal asphyxiation if precautions are not properly implemented.
The myth that someone who is drowning will always shout for help and wave their arms is not accurate. Drowning is often silent and swimmers in distress are usually unable to call out for help as they are focusing on trying to breathe or keep their head above water. Recognizing the signs of drowning and understanding the risks of activities like autoerotic asphyxia are critical for prevention and safety.
