@Ragman,
I mean irrational in that it is so unlikely to occur.
Like being afraid of getting sucked into an escalator and killed - not likely to happen and then you hear of it....
Chinese mother saves son seconds before falling to death inside escalator
Security camera footage has emerged of a mother saving her young son's life seconds before losing her own on an escalator in China.
The 30-second video begins innocently enough: As the escalator in a shopping mall almost reaches the top, a woman in a white shirt and black skirt lifts up her young son to get ready to step off.
But as she does, a metal panel collapses under her feet. She falls into the gap.
Chinese state media on Monday named the woman as 31-year-old Xiang Liujuan.
Struggling with only her upper body above the metal structure, Xiang is seen pushing her son forward. The boy is quickly pulled to safety by a mall employee standing near the top of the escalator.
Two other mall employees try to drag Xiang out, but within a few seconds, she disappears through the hole into the escalator shaft.
