The sustaining of life, in a bodily sense as well as in the sense of psychological health, is inherently subject to risk.

The body is thus not simply an 'entity', but is experienced as a practical mode of coping with external situations and events.

A lifestyle involves a cluster of habits and orientations, and hence has a certain unity - important to a continuing sense of ontological security - that connects options in a more or less ordered pattern. (...) [T]he selection or creation of lifestyles is influenced by group pressures and the visibility of role models, as well as by socioeconomic circumstances.

The flow of action continually produces consequences which are unintended by actors, and these unintended consequences also may form unacknowledged conditions of actions in a feedback fashion. Human history is created by intentional activities but is not an intended project; it persistently eludes efforts to bring it under conscious direction.

[C]ultivated risk-taking represents an 'experiment with trust' (in the sense of basic trust) which consequently has implications for an individual's self-identity. (...) In cultivated risk-taking, the encounter with danger and its resolution are bound up in the same activity, whereas in other consequential settings the payoff of chosen strategies may not be seen for years afterwards.

The thesis that risk assessment itself is inherently risky is nowhere better borne out than in the area of high-consequence risks.

Abstract systems depend on trust, yet they provide none of the moral rewards which can be obtained from personalised trust, or were often available in traditional settings from the moral frameworks within which everyday life was undertaken. Moreover, the wholesale penetration of abstract systems into daily life creates risks which the individual is not well placed to confront; high-consequence risks fall into this category. Greater interdependence, up to and including globally independent systems, means greater vulnerability when untoward events occur that affect those systems as a whole.
