Stress. It is a word that affects nearly everyone living on the planet. By everyone, it implies that only humans are included. Animals do not have stressful lives like we humans do. It’s not that they do not have any stress, as anything that has emotions has the potential to experience stress. However, in the case of animals, stress is a result of external factors such as the need to hunt a prey before starving out or the constant watch to be kept over their new born. The stress experienced by humans is more of a result of their own thoughts, fear, and inhibitions.
