Methylation is changes slowly throughout the life, the strongest predictor of age inside the body (that's why it's used as an aging clock). This also means that it may be the most important thing to learn to manipulate to defeat aging. Also it's the cause of many non-genetic chronic diseases that come with age. In summary it's a really really important thing to study. https://en.wikipedia.org/wiki/Epigenetic_clock#Properties_of_Horvath's_clock https://en.wikipedia.org/wiki/Epigenetic_clock#Properties_of... There are other hallmarks of aging though: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3836174/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3836174/
