Despite established evidence that social conditions are biologically embedded in DNA methylation patterns (e.g., GrimAge and DunedinPACE clocks), there is a glaring blindspot in current longevity research: the biological impact of algorithmic social curation.

My hypothesis is that engagement-maximizing algorithms systematically expose users to high-arousal negative content (such as moral outrage and social comparison threats), inducing a state of chronic social stress. This distinct form of "digital social adversity" likely accelerates epigenetic aging through inflammatory pathways, particularly IL-6, which is highly responsive to chronic stress and a core component of epigenetic clocks like GrimAge.

While traditional social adversity (economic hardship, social isolation) has been validated as an accelerator of epigenetic aging, the field has yet to empirically test whether the 3-6 hours of daily algorithmic exposure experienced by billions functions as a novel "digital social determinant" of health.

I propose we need longitudinal studies tracking DNA methylation changes in cohorts exposed to different algorithmic engagement profiles. Does the algorithmic optimization for outrage directly shorten healthspan? How do we quantify the metabolic cost of the modern digital ecosystem?
