I was afraid you might say that.

Well, cause is cause, so I suppose it is really all preventable or avoidable given the proper context. As an insurance claims adjuster pal of mine once quoted "in 99.9999% of all traffic accidents everyone involved was at fault somehow". His rationale being that they could've all chose not to drive that particular stretch of road at that particular time.

Being somewhere else at the time; is that part of the axiom "Chance favors the prepared mind"? or maybe a variation thereof...
The ultimate result of shielding men from the effects of folly is to fill the world with fools.
-- Herbert Spencer, English Philosopher (1820-1903)
