I was going to say that xD
Smoke and carbon monoxide detectors
The mind boggles
Flashlights with extra batteries or other emergency lighting for when the power goes out.
Yep. After growing up on a remote farm, you know the importance of light when the power goes out.
Sometimes, growing up, we'd be without electricity for a week. Nothing like pumping water from the well using the hand pump in the yard and using kerosene lanterns at night..... (Wouldn't mind going back to that sometimes.)
Smoke alarm, fire extinguishers.
Sad to say, a computer.
Oh let me see a toilet a bed a microwave a stove and a sink and a way to make coffee is all I really need to survive.
