Given this mother's astounding lack of common sense, I think her children's life expectancy may have been extended by her death. Even if she just wasn't aware of the dangers of excessive water-drinking whne she decided to participate, she'd apparently been listening to the proceedings on the program, wherein a caller warned that this could be fatal and one of the DJ's responded with "Yeah, we know". When she started having a nasty headache, wouldn't it have been a good idea to call 911 or flatly order the DJ's to do so? Would she have thought to call 911 if one of her children started feeling really sick shortly after doing something that she'd been warned could be fatal?
Too bad the caller who gave the warning didn't follow up with a call to police and/or 911 after the smart-ass response from the DJ.
The water drinkers were being kept apart from the broadcast, in a different room.
