Centenarian Self-Perceptions of Factors Responsible for Attainment of Extended Health and Longevity
Bibliographic record
Abstract
Pathways healthy and physically functional centenarians take to achieve advanced old age have fascinated mankind for centuries. This hermeneutic phenomenological study documents characteristics perceived by centenarians as important and central to their attainment of advanced longevity. Secondary data including written transcripts and audio and video interviews were collected from the Internet for 19 centenarians ranging in age from 100 to 115. Four themes were identified and described: (a) lifestyle choices, (b) community and environment, (c) goal setting and attainment, and (d) attitude towards life. Centenarians credited tangible, easily understood personal lifestyle choices for their attainment of advanced longevity. No consensus was found between the current analysis and major themes identified in a literature review from quantitative studies. Future research should include qualitative analysis utilizing primary interviews of centenarians and mixed methods studies designed to explore the differences between the current qualitative and quantitative research findings.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
