Older adults with a strong sense of purpose showed measurably slower epigenetic ageing on several DNA-based biological clocks — an association equivalent to roughly two years of biological age between people with high and low purpose, though researchers cannot yet say purpose itself caused the difference.

A stronger sense of purpose was associated with younger readings on four DNA methylation clocks in a U.S. sample of older adults. Across those clocks, the median model-based difference between people at the high and low ends of the purpose scale was about two years.
This is one study, not settled consensus. The analysis was cross-sectional, so it cannot show that purpose slowed aging. It also found no association on nine other clocks, and the four significant relationships disappeared after the
