>Farming work is (or used to be, before modern farming techniques) seasonal, and can be quite very light for the better part of the year. Professions like doctor, store owner, merchant etc didn't require anyone to sit 8+ hours straight in some cubicle. Shops (in 19th century Paris or Chicago or London etc) weren't optimized to serve tons of customers as fast as possible like a modern chain. Small towns and villages -- where most of the population (the rural) in any country lived before 19th century -- were far more leisurely too.

You can kind of see this transition happening if you visit currently-industrializing countries like India or China.
