BTW, having many different jobs and diversifying wasn't unusual for farmers in the antiquity. A Roman farmer with a little plot of land would tend to his own vegetable and fruit garden, and maybe have a small cereal field, but he wouldn't be able to survive on those alone. So he would occasionally work in the mines, and would surely help out the large landowners during harvest seasons. This way he was paid in money, with which he could buy ready-made clothes, pottery, and food.
