Fifty-five source-reviewed stories explain what human studies, early
trials, biomarkers and laboratory research can—and cannot—tell us
about healthier aging.
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.
The newest findings—and what they mean for healthy aging.
Each story names the studied population, outcome, limits, safety
context and sources—without turning a promising signal into a
longevity promise.
Research Analysis
Health & function
STRIDE did not significantly reduce serious fall injuries in primary care
In 5,451 older adults at increased fall-injury risk, a nurse-led multifactorial strategy did not significantly reduce the first adjudicated serious fall injury versus enhanced usual care. A secondary self-reported fall-injury outcome differed.

LiFE reduced self-reported falls by embedding activity in daily routines
Among 317 selected older adults at high risk of falls, the LiFE program integrated balance and strength activities into everyday routines and reduced the self-reported fall rate versus sham gentle exercise over 12 months.

A tailored Tai Ji Quan program reduced falls in one high-risk trial
In 670 selected community-dwelling older adults at high risk of falling, a therapeutically tailored Tai Ji Quan program reduced falls over 24 weeks versus stretching and multimodal exercise.

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.

ACCORD’s intensive glucose target increased mortality and was stopped early
In 10,251 adults with type 2 diabetes and high cardiovascular risk, an intensive multi-drug strategy targeting near-normal glycated hemoglobin did not significantly reduce the primary cardiovascular outcome and increased all-cause mortality.
