I did all sorts of hardcore farming work when I was a kid in Mexico.
Imagine being an American 5 year old, your days filled with cartoons, ice cream trucks, kindergarden, coloring books, etc.. All of a sudden your family moves to Mexico and you now spen your days feeding and hearding cattle, planting corn, cutting fire wood, building fences with big rock boulders, etc... basically adult level work. Wakingup at the crack of dawn, and working all the way up to sun down. Luckily I only experienced this up to the age of 9, when we moved back to the US.
