// A more involved example that resembles a simulation of sorts.
// The simulation is of a miner, who wants to earn 3 gold
// In order to get gold, they need to sell metal at the Merchant
// And in order to get metal, the miner needs to smelt some ore
// And in order to get ore, the miner needs to go out, find ore and mine it
// And besides those requirements, the miner also have hunger and energy
// that constantly change, and they need to sleep and eat in order
// to satisfy those needs.

// Put another way, the miner has to:
// Eat and Sleep every now and then
// Mine to get Ore
// Smelt Ore to get Metal
// Sell Metal to get Gold
