Spending your whole life doing back breaking hard work, tilling soil, planting seeds, hoeing weeds, harvesting, eating and sleeping. Rinse and repeat for years on end, with nothing to show for it except that you've managed to stay alive, all just to die of skin cancer at the age of 65 from being out in the sun all day (or from being around so much fertilizer and insecticide chemicals). Sounds fulfilling!
