From New Scientist…
AS if being bottom of the social pile isn’t bad enough, it now seems that it also makes the body’s cells age prematurely.
People from lower socio-economic groups are more likely to die earlier than people in non-manual jobs from heart attacks, strokes and cancer. Unhealthy habits such as lack of exercise, excess weight, smoking and poor diet account for around a third of these deaths.
Now, a study on white blood cells from 1552 female twins suggests that cells from women with more menial jobs age faster, even after taking these factors into account. On average, their cells were seven years “older” than those from women of the same chronological age with non-manual jobs.
