Well earned Rest

Peasants Resting by Jean-François Millet

I'm quite dissatisfied with the generic  "You recover 1d3 HP when resting for a day" mechanic.

Here's what I've been using:

• You recover 1HP for a full 8 hours night of sleep, with no interruptions like taking guard turns.
• You recover 1HP for a day spent resting without doing tiring activity. Watering a garden, carving a toy out of a piece of wood or fishing is light activity, while working in the fields, repairing a roof or hunting is clearly not.
• You recover 1HP if you have at least one healthy, warm meal that day. Field rations eaten on the way do not apply, but a soup made from wild roots and fresh fish eaten with some wine counts.
