Current scientific literature supports the protective role of positive psychological states like optimism in mitigating biological aging, showing that psychological well-being helps buffer against cellular aging markers such as telomere attrition.

The analysis

The provided papers include studies demonstrating that psychological stress accelerates aging pathways [4], and specifically that optimism acts as a protective buffer to preserve telomere length against adverse environmental stressors [5]. No papers directly refute the claim, leading to a SUPPORTED balance verdict.
