An EMP event would instantly destroy any means of telecommunication, bank account would disappear, planes would fall from the skies, nuclear plants would not be able to cool down the reactors, we would have no running water (water pumps) and every piece of electronics we use from pacemakers to phones to gasoline pumps would stop!
Your refrigerator will stop working and all your food will spoil in a matter of days! If you and your family are not together, you won’t be able to contact or see them.
NOT a good day :(
And my laser sight would stop working too...
