London: A stressful job could make you old and sick before time, as a new study suggests that people with high stress work tend to have shorter telomeres, which has been associated with several diseases. Telomeres, located at the ends of chromosomes, serve as a type of protective cap to the ropy strands and their shortening has been linked to Parkinson`s disease, type 2 diabetes, cardiovascular disease and cancer. The research led by Kirsi Ahola of the Finnish Institute of Occupational Health measured the length of DNA sections called telomeres and how the lengths varied in association with job stress. The study found that people suffering from the most job stress tended to have shorter telomeres.
