Researchers discovered that our genes have a much greater influence on how old we become than was previously assumed. Until now, scientists assumed that mainly our living environment and chance determine how long we live. A new study by the Weizmann Institute shows that genes may even account for half of the difference in lifespan.
The study examined extensive data from twins, including so-called dizygotic twins who were raised apart. By applying clever computational models, the researchers were able to exclude deaths caused by accidents and other external factors. This made it clear that hereditary factors play a larger role than was previously recognised.
These findings provide new insights into why some people live to a much older age than others, even when their lifestyle and environment are similar. It highlights the importance of genetic research in understanding healthy ageing and preventing age-related diseases.
In the longer term, this knowledge can contribute to better prevention and potentially also personalised advice that takes a person's genetic predisposition into account. That makes it a valuable step in promoting a healthy and active old age.
This research shows that heredity should not be underestimated in the pursuit of a long and healthy life.
