I see, thanks. Could approaches like Horvath's phenoage/grimage (which I think go after methylation) be good enough proxies for the "transposon clock" or somewhat correlated but different things? 

What might the best ways of transposon quantity/activity approximation methods for this effect that are average human affordable & accessible?

Wondering if correlation data collection can be taken to a different scale + the concept can be popularized as a self-care metric.
