I find that when I go camping, I get sleepy early around 9pm and I wake at 6 feeling more refreshed than I do at home. Fresh air and birds chirping. It's honestly a dream

Lighting was the killer app for electricity.

Electricity costs money too? I don't know how the cost of power compared to the cost of a candle in the beginning of the 20th century though.

You can make and light a long-burning torch from the materials found in most any lush yard, let alone the much greater areas of wilds available to people in the past.
