Adverse moments are high Zones of Vulnerability. Dark ages. All that was working thru times, doesn't suddenly work. What will actually work further into the future, lies dormant in the realms of the unknown.
The friables, the brittle and the fragile collapse and break-down never to rise again. Too scared & scarred to rise. The strong, the robust and the resilient fall too. But they get up to recover fast and fight another day without reflecting cracks or scars to remind them of their falls.
Human fragility thrives on ego. Bigger the ego, more fragile and friable the person. When systems collapse, the egocentric fall and fail to recover. The robust like Gold, get up and fight.
