Stubbornness, a refusal to give in to problems and obstacles that face you, will give you the mental and physical strength to endure. The natives and animals of a region have adapted to their environment. To get a feel of the area, watch how the people go about their daily routine. These actions are important to you when you are trying to avoid capture. Animal life in the area can also give you clues on how to survive.
Animals also require food, water, and shelter.
By watching them, you can find sources of water and food. Animals cannot serve as an absolute guide to what you can eat and drink. Many animals eat plants that are toxic to humans. Keep in mind that the reaction of animals can reveal your presence to the enemy. If in a friendly area, one way you can gain rapport with the natives is to show interest in their tools and how they get food and water.
