I think everyone should turn off their power for a couple of hours (when convenient) just to see if and how well they'd manage. Because it's so easy to become reliant on something without realizing that it could go.

Powers gone off? Guess I'll put the kettle on and make some tea while I wait - no power. It's got a bit dark - put the light on. Listen to spotify? No songs downloaded and no data etc etc. And that's not even covering food preparation yet.
