Calories burned: 7-10 calories per minute for work like bailing hay and shoveling grain.
The Work: Was varied and difficult, exhausting the farmer and inducing sleep by dark. Technological advances in agriculture made life slightly less difficult over the years, helping farmers to avoid expending more energy than they could spare on caring for their land.
Accessibility: Not too high for most, unless you crave a dramatic career and life change. Still, it’s a much more active work lifestyle than any desk job, and far different from the rat race most are familiar with.
