There's a big difference between being in a field versus working in a field, from dawn to dusk, every day, regardless of the weather or sickness, in order to produce just enough food to feed you and your family, knowing that a single failed harvest (due to conditions like weather and pests that you have no control over) will leave you starving, watching helplessly as your children, spouse, friends and neighbours slowly weaken and die, knowing that even if you survive, you will face the same thing again the next year, and the next, for the rest of your lives, which will likely be short, due to the constant, exhausting labour, frequent bouts of malnutrition, and nonexistent medical care.
