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.
When cells want to keep dividing, they do have a mechanism to lengthen their telomeres. They use a special enzyme called telomerase. So, a fetus has active telomerase in each of its cells.
