As We often say, Rhinos depend on Scent to keep Us current, which can be a L&D Matter. In the Wild.
What also should be noted is that the Air We breath has no Natural smell of its own. Whatever it’s made of, Air serves as a neutral vehicle for presenting Scent. It carries all sorts of information, long distance or short, and gives Us Rhinos a head start for our Computations and Responses.
Air. We can’t see it, smell it, or taste it, but We sure can’t function without it.
