How does food affect our health and lifespan? That’s a complicated question because it’s hard to isolate the intake of one nutrient—in this study, researchers try to answer this question.

Avoidance of excessive blue light exposure may be a good anti-aging strategy, as blue light interferes with vital metabolic pathways that are key to aging human cells and flies.

Slower biological aging is associated with longer lifespan and healthspan, as seen by women who lived to age 90 without physical or cognitive impairments—turning the term nonagenarian into “non-agerians”.

Saliva-based biological age tests on the market have seen dramatic drops in price points with increased accuracy, making biological age testing more accessible for the average consumer.
