It’s a bit strange to think about, but our brains seem to have adapted to information accessibility today by more readily remembering how to find the information instead of the information itself. (See Betsy Sparrow et al)
If you lived back then, chances are you’d just straight up remember more things without needing to go look them up again. But, you might also just remember what book you found it in.
I have wondered if this is part of the reason why ancient orators were apparently capable of reciting hours of dialog from memory. They simply had to. Libraries and books weren’t generally accessible. They had to rely on memory, and thus became very trained on it.
Try looking for crops to grow that are nutritious but relatively low maintenance. Sweet potatoes, sunchokes, groundcover strawberries, asparagus, cherry tomatoes, etc. Bonus if you can grow excess to sell at local farmers markets for some extra income, though the easiest the grow ones probably won’t fetch a great price and on one acre I doubt you’ll have extra of anything. Also, look for native options. Less maintenance, and local pollinators are more likely to help out.
If you’re not squeamish and can get enough extra space with an enclosure, rabbits breed very quickly and just eat grass. Chickens are good for eggs and meat.
