Memory, focus, and staying mentally sharp over decades.
Chris Hemsworth said“I carry a high-risk Alzheimer's gene, so I lean on exercise, sleep, and stress control to fight back.”
The science saysSupported. Big studies link regular exercise to meaningfully lower dementia risk, though they cannot promise it for any one person.
Verdict: He can't out-run his genes, but he can make them sweat.
David Sinclair said“Taking resveratrol every day helps slow down human aging.”
The science saysNot established in people. Resveratrol extended life in mice on a rich diet, but human trials and a failed drug program never showed the benefit.
Verdict: Spectacular in a mouse, unproven in a professor.
Bryan Johnson said“A strict protocol of food, sleep, exercise, and more than one hundred daily supplements can measurably slow how fast you age.”
The science saysNot established. The basics help, but slowing human aging with a large supplement stack is unproven, and a routine of one person cannot prove it works for anyone else.
Verdict: Measure all you want. The anti-aging headline is running ahead of the evidence.
