True Fact: Each and every Rhino is always changing. We go to bed one thing, and awake another. We go to bed somebody else. Better or worse is not the point here, just the inevitability of change.
We can only conclude that this is how Nature has Us mapped out. This is the plan, whether Rhinos notice it moment to moment, or not.
This way, there is no point in getting too snarled up about anything. Inside, outside, We are about to be somebody else.
