Younger fathers may be able to keep up with their kids in the playground, but a recent study has found evidence that older fathers may pass on longevity to their children. It has not been proven yet, but the study does show some really interesting evidence.
The study was developed by several professors at Northwestern University in Evanston, IL and University of Washington in Seattle, WA. This interesting study revolved around “telomeres” which are structures at the end of chromosomes which protect the chromosome from damage.
Telomeres have been linked to the aging process. Shorter telomeres have been linked to a shorter lifespan while longer telomeres have been linked to longer lifespan. These structures become shorter over time in all areas except for within a man’s sperm where they actually get longer over time!
This study focused their research on blood samples of over 2,000 people in the Philippines. The researchers discovered that telomere length was inherited by children AND their children’s children! This means that an older grandfather could pass the longer telomeres to both their son and grandchild!
It’s a fascinating study that provides some real good insight into the aging process. It does NOT mean that men should wait until they are old to have children – there are also mutations that develop over time, but it is a promising study that is potentially unlocking another secret to the world that we live in.
