People with lifelong GH deficiency avoid both — and GH given to healthy older adults raises harms without extending life.

A 2022 study found technical noise alone could shift the result by up to 9 years between replicates of the same sample.

Participants never hit the 25% target.

The first year-long randomised trial of a spermidine supplement found no effect on memory.

A separate line of work argues the world's longevity hotspots track missing birth records and old-age poverty — not diet.

The mouse work suggests diluting old blood may matter more than adding young blood — and regulators warn the paid infusions have no proven benefit.

Across 183 countries the healthspan–lifespan gap instead grew to 9.6 years, and to 12.4 in the US.

No human study has yet shown the diet prevents disease or extends life.

At age 75, predicted 10-year survival ran from 19% to 91% across the range — but speed reflects health, not the reverse.

The largest cohorts show most of the benefit arrives at half the recommended dose, and more brings diminishing returns.

The framework is the field's shared map — but critics argue it describes ageing without explaining it.

In people it fails to reliably switch on the enzyme it targets, and higher intake tracks no drop in death, cancer or heart disease.
