However, the exact mechanism by which stress has a body and remaining physically Omar is still largely unknown, but his impact on the rate of cell aging. New data from the investigation point to a specific mechanism in our cells that may be behind the pressure and stress-related aging processes. Each chromosome in the body is protected class repetitive DNA known as telomeres. These telomeres work the same way that the tip of the plastic on the end of the shoelace and prevent chromosome becomes brittle and damaged. As we age, our cells divide through the split, shorten telomere length after each division. This process directly linking the telomeres in the aging process.
