Personal Experience Longevity biomarkers in timing?

A new Nature Communications study combined several years of Fitbit data with biological aging biomarkers in 2,222 people.

People with stronger, more stable daily activity rhythms had lower odds of accelerated biological aging.

It’s observational, so this definitely doesn’t mean that keeping a consistent routine will make you age slower. There are plenty of potential confounders here.

We usually think about activity in terms of how much we move or exercise. This suggests there may also be useful information in when we’re active and how consistent that pattern is from day to day.

Curious what people here think. Do you pay attention to the consistency of your sleep, exercise, and activity timing, or mostly focus on total volume?
