Chronic stress accelerates premature aging by shortening DNA telomeres. A wide range of studies have shown that the stress caused by things like: untreated depression, social isolation, long-term unemployment, anxiety attacks... can speed-up the aging process by shortening the length of each DNA strand.
After many divisions, the telomeres become depleted and the cell begins apoptosis. This is a mechanism that prevents replication error that would cause mutations in DNA. Once the telomeres are depleted due to the cell dividing many times, the cell will no longer divide and the Hayflick limit has been. reached.
