In the Wild, We Rhinos have to watch our step. The occasional bump or bruise just goes with the territory, perfectly Natural. But there is a serious Limit.
In the Wild, there is no medical attention, no sick leave. In the Wild, We have to keep moving; if you sit in one place too long, some critter is likely to come take a bite.
We must do what We can, as long as We can, Naturally.
