not possible, a walkman works with AA battery, that's not enough electricity to die or even received a shock from that. Some people died with hairdryer and things like that though
and I mostly agree with you that it has to do with parenting. When I called it "millenials' natural selection", I meant that it's the new way to eliminate stupids from the society, not that it has to do with the girl who died being a millenial.
I never heard my parents telling me to not do that because it was dangerous but I knew it was. If your parent needs to tell you as a teenager that you should not put your hand in boiling water, it's not necessarily good parenting but more like you're stupid to begin with.
What I mean more precisely is, children need to be taught restraint. You say attachment to phones is a thing, but is it a good thing? Would it be a thing that should be prevented or restricted? I think maybe so.
