Stopping smoking was associated with lower mortality at every age studied
Two large observational analyses found substantially higher mortality with current cigarette smoking and lower excess mortality after stopping. The estimates describe populations; they do not promise a particular person extra years.

DPP prevention effects persisted for 15 years—without an overall microvascular difference
Among adults at high risk for type 2 diabetes, the DPP lifestyle and metformin groups still had lower cumulative diabetes incidence after 15 years. The randomized groups did not differ significantly in the study’s aggregate microvascular outcome.

Look AHEAD improved weight and risk factors—not cardiovascular event rates
In 5,145 adults with type 2 diabetes and overweight or obesity, intensive lifestyle intervention produced greater sustained weight loss and improved several risk factors. It did not significantly reduce the trial’s primary cardiovascular outcome.

Sauna use was associated with lower mortality—not proven to extend life
One Finnish male cohort linked frequent sauna use with lower mortality. The design cannot show that sauna caused longer life, and randomized evidence has not tested that endpoint.

CBT-I improves later-life insomnia—not aging itself
Two randomized trials support meaningful sleep improvement in older adults; they did not test dementia prevention, biological aging or lifespan.

LIFTMOR found BMD and function gains in a small, screened, closely supervised trial—not fracture prevention or proof that unsupervised heavy training is safe.

The MIND diet trial found no cognitive edge over its active control
Both groups improved with counseling and calorie restriction; the between-group cognitive difference was not significant and MRI measures were similar.

Different eating windows and comparators produced different weight and fat findings; none tested biological aging, healthspan or lifespan.

LIFE supports a meaningful mobility outcome in vulnerable older adults, while lifespan and universal-program claims remain untested.

Duration, regularity and fragmentation carry health signals, but the featured studies do not show that changing one metric extends lifespan.

The corrected randomized analysis is promising for its composite endpoint, while allocation deviations and lifespan limits remain visible.

A randomized trial found selected cardiometabolic improvements, while aging-biomarker results were mixed and lifespan was not measured.

Human trials support mobility and physical function in defined populations. Lifespan and biological-age claims require separate evidence.
