From what I gathered from the bit I watched, it looks like the seasons are moving right along, so it would impossible for them to live there, I would think - different from 1940's house, say, where they could artificially move the war along and show the changes in conditions over just a few weeks. Hard to do that with things like lambing and planting and growing of crops, unless they didn't have to go to work in their 'real lives'. Still, an interesting look at what life was like back then...
