Is there any way to tell whether people living in previous eras back to prehistory were more or less scared/fearful of life/universe on average than we are? Is there a fear treadmill where we are at a fear homeostasis?

Like cortisol levels in mummies or something? Though that one would show us as more chronically stressed. Fear of universe = frequency of moments of acute stress maybe. Lion chasing you, God’s cursing you, lightning, toothache...
