In Russia we had a lot of training for 'incase a powerplant explodes and released toxic gases'. And I kept hearing these stories about it...
People were telling me things like "When the powerplant explodes we would all have to wear the gasmasks, even when we sleep, and even eat wearing them".
This eventually made me belive that there is only one powerplant on earth which one day WILL explode... like it is unavoidable and it will explode, people are just basically waiting for the unavoidable disaster to happen ( just like a meteor strike)
And I belived that when it explodes, the gases would ALMOST INSTANTLY fill the ENTIRE EARTH and we would have to live with gasmasks for the REST OF MANKND. xD
