Just to remind myself:
Something “Constant” exists only on paper or in silico.
In life “Normal” = Variation
Variation can be Random or have a Trend, but even the Trend Fluctuates and is never Constant.
If this is true then the terms “Constant” and “Life” are incompatible. And consequently, “Living a Normal Life” cannot possibly be Defined.
