From my own experience time went slower when I was a kid because we didn't have deadlines or the worries we have now. Summers went by fast and the school year dragged on. When I became a teenager time dragged by because I was waiting to be 18 because I thought there would be some miracle of adulthood attached to it.
My grandmother worked her little hiney off raising kids, preparing food for storage and meals. Making and repairing clothes and worrying if there would be enough money for shoes. Grandad plowed the fields for grain for their livestock with a workhorse and plow. There were tractors but he couldn't afford one or the gas to run it. Before he could plow he had to clear a field by cutting down trees that were cut up for firewood, and using dynamite for the stumps. He looked older than his years because he worked from morning til dusk and your body does wear out. After all was said and done he said he wouldn't change a thing.
