Stress can make your cells die faster! Scientists have ran a study on if stress will shorten your life. They got 58 healthy women and ran tests and asked them on a daily basis how much stress there was. They've actually figured out there is a part of DNA called a telomeres and stress will shorten them. In a cell, telomeres are responsible for the dividing of cells, when there is no more telomeres the cell will eventually die.
I think that this is a real great discovery. I thought I had a lot of stress, now i know to try not to get stressed out. I think i am even going to tell my mom about this. With all the kids she has she needs this information.
telomeres-region of repetitive DNA at the end of chromosomes, which protects the end of the chromosome from destruction
telomerase- an enzyme that adds specific DNA sequence repeats to the 3' end of DNA strands in the telomere regions, which are found at the ends of eukaryotic chromosomes
provocative- causing annoyance, anger, or another strong reaction, esp. deliberately
