It's one thing to listen to this through a RU-vid video. But, can you imagine waking to this at 2:48am and it be an actual emergency? The depth of shit in your pants would be overwhelming!
My grandparents had to go through with that. They fell asleep with the radio on one day and they woke up to a blaring noise coming from it. The power plant near their area was about to fail and meltdown. Luckily it was stopped before anything major happened. Every since that night they've left the radio on when they're in the bathroom, in bed, or even in their living room.
