Escape from fragility

‘Escape from fragility’ is the realisation of a state that moves one away from fragility. Fragility is the danger to become dysfunctional. A high escape velocity away from essential body system fragility is quasi-immortality. It is known as longevity escape velocity. It refers to working capacity longevity, not mere bodily sustenance. 
* Osteoporosis treatment is to escape bone fragility. 
* Cybernetics involves escaping system fragility.
* Statecraft involves escaping State fragility.
The inverted pendulum is used as an example to illustrate controller fragility under minimum norm state feedback. The stabilization process gets trapped in a cusp. A parameter space representation shows a safe escape. [ Kaesbauer 98 ]
