quoting myself from elsewhere:
I think the following axiom is fit;
only excess of strength is proof of strength.
I think that is Nietzsche.
Only excess of health is proof of health.
Excess is the range in which things come into being, acquire distinct forms to our perception.
So we live in a wholesome age, the selfie-age has its merits. It is required to radiate excessive health of body in order to be selected. The standard has become somewhat more like a fruit-standard. Its no longer as abstract.
Extrapolate this to the planet.
