PREDICTORS OF LIVING TO AGE 90 AMONG THE MEN OF MANITOBA FOLLOW-UP STUDY
Bibliographic record
Abstract
A cohort of 3,983 young male aircrew recruits from the Royal Canadian Air Force has been followed with medical examinations and regular contact since 1948. In this cohort 98% were born in 1925 or earlier, and hence had the opportunity to live to age 90; 745 (19%) did. A history of childhood illnesses was recorded at entry to the study, mean age 30 years. EKG abnormalities, anthropometric measurements, and disease diagnoses were recorded at routine physical examinations over 68 years of follow-up. Physical activity was surveyed at ~50 years of age, and physical and mental functioning were documented on annual surveys since 2000. Smoking history, blood pressure and body weight at entry; absence of smoking, major ekg abnormalities and excess weight at mid-life; and continuity in mental functioning in later life distinguish the men living to age 90. The life course perspective is invaluable for long-term research.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
