> It seems no one can answer this
Good. It's metaphysically impossible to answer, and would only serve weak minds who like to think what 'could' or 'should' be done. Since it cannot be done even twice, the moment you do it stops being the correct answer. It's a fact that can only exist in the unrealized future, therefore it's not really a statement of fact. You could expand it to 'any human' and establish a fact, but then you have to define 'existing humans'.
