Independence: A New Reason for Recommending Regular Exercise to Your Patients
Bibliographic record
Abstract
There are many good reasons to advise regular and adequate physical activity: longevity seems extended by up to 2 years, and the risk of a wide range of chronic disorders is substantially reduced. However, from the viewpoint of the overall, quality-adjusted lifespan, perhaps the most important reason is the ability of physical activity to counter the relentless, age-related decrease in physical capacity (maximal aerobic power, muscle strength, flexibility, and balance). The case is detailed for maximal aerobic power, which deteriorates by about 5 mL/ [kg x min] for each decade of adult life. Independence is generally at risk when the maximal oxygen intake has dropped to 18 mL/ [kg x min] in men and 15 mL/ [kg x min] in women. A sedentary person typically reaches this threshold between 80 and 85 years old. However, regular physical activity can augment maximal oxygen transport by 5 to 10 mL/ [kg x min], setting back the need for institutional support by 10 to 20 years.

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.
