Learning on the job, the use of selection, optimization, and compensation strategies, and their association with telomere length as an indicator of biological aging.

Resources at work were weakly associated with telomere length, which is not unexpected in view of the multiplicity of factors affecting LTL. The results further suggest that a mismatch between SOC and learning opportunities may negatively affect successful aging. They also suggest that more detailed research on biological aging and its relation to resources at work is needed.
