Sounds about normal to me.. except for the 30 years part.I actually grew up without running water or electricity. Our only heat was a wood stove and we had to haul water. We didn't have lights, we used one candle after dark. We had an outhouse for a toilet, and in the -40F winter the inside of your nose froze when you went outside. Even then we were pampered by comparison, but it was a taste.
One winter we ran out of fire wood in the middle of the week and our neighbors from a few miles away hauled some over for us on a sled. I don't know what we would have done, since we didn't have money to buy food we certainly couldn't buy wood. The next weekend, when it was light my dad could go cut down more wood.
So, yes... You definitely depend on others.
Edit: btw, this was about 30 years ago!
There are a few people on here who predate electricity. I don’t want to name them though. But they know who they are.
