It's important to note that this is a preliminary finding, based on weak evidence, and that "creativity" is not necessarily the core concept of "openness" in the OCEAN five-factor model of human personality. The "big five" personality model is still developing,

and "openness" is the most poorly defined of the five personality factors in the model. It is plain, on stronger and better replicated evidence, that the factor "neuroticism" is a risk factor for many bad outcomes, including shorter lifespan. Some investigators have proposed specific interventions to reduce neuroticism in the general population.

The relationship of "openness" to creativity is still debatable, and still more debatable is the relationship of openness (or creativity) to mortality.

I should also note that the study described in the article kindly submitted here doesn't allow for the causal inference, or verify the proposed mechanism, made in the quoted statements in the article.
