Yes. I wouldn't call it desirable but certainly doable.
My grandparents didn't get electricity or an indoor toilet until I was 4 and had gotten along fine for 50 odd years.
My folks got along with a pitcher pump and outhouse for a year... and kerosene lamps for a couple months.
Anything more than a cave and a brontosaurus bone to gnaw, is luxury.

If you didn't have electricity where did you plug in your PC? I freak out when my Internet goes down. I could not live without electricity.

I guess Red Dawn wasn't about you.

The house I grew up in, two up two down, had neither electricity, gas, sewerage services or water. We had a 'wash-house' in the back garden with a hand water pump delivering cold hard water, and a 'privy' at the end of the garden shared by three other cottages. The wash house also housed a copper, literall a big water boiloer which we lit a fire underneath on washday in order to boil wash the whites.
My mother cooked on a range fuelled by coal and wood and we used oil lamps, candles and later, gas mantles for lighting. That's coal gas not the sort cars run on. We had a pressed earth floor which I recall being so cold in winter... And no we didn't glow with rude good health, I seem to think we had perpetual runny noses and chilblains.
Makes you think about how very many advances there've been of the purely domestic variety which are now commonplace. I don't want to be without my satellite link or my wireless internet but things like hot water and phones and a flushing indoor loo are just basic aren't they.

CzinZumerzet: Interesting story! Where did you grow up?

I am guessing in a cave hiding from dinosaurs. :D
