In the Wild, Hunger is not addressed at ‘mealtime’. There is no ritual to food consumption. All Critters take hunger seriously and address it, or starve. For those who have not faced that prospect, let Us Rhinos say, “It’s no joke.”
What helps is that Nature often has secret stores of food, one place or another. This is when the RhinoSense of Smell kicks into gear, saving the day. An encounter with a shrub is Welcome; it can be a LifeSaver.
This race goes to the Swift and Attentive. We are talking about Survival.
