The rearrangements may be due to an unusual configuration of telomeres, the caps at the ends of chromosomes that protect them from sticking to each other.
Other research has shown that PPIs may shorten the protective chromosome ends known as telomeres, in effect speeding up cell aging.
Many scientists believe that longer telomeres signify longevity.
Telomeres are the tips of chromosomes that protect DNA while it's being copied -- like the aglet at the end of a shoelace that prevents it from fraying.
In one study conducted recently by Brigham Young University, researchers found that people who exercise regularly at a moderate to high intensity actually have longer telomeres in their DNA.
These telomeres are a string of DNA proteins that rest at the end of a chromosome.
Others believe the key is to repair telomeres, the sequences at the ends of each chromosome that unravel with stress and age.
Researchers looked at the telomeres from nearly 6,000 adults enrolled in a multi-year survey run by the Centers for Disease Control and Prevention.
