Do Older Dads Have Healthier Kids?
Men who chose to have children later in life have gotten a lot of heat recently, with research churning up evidence that the older a man’s age at time of reproduction, the greater the risk of autism, schizophrenia, and other disorders in their kids. But a new study, published in Proceedings of the National Academy of Sciences, may have identified a health benefit that older dad’s bestow upon future generations—longer telomeres. Telomeres, the ends of linear chromosomes that serve to protect the coding DNA of the genome, have been linked to several diseases, including cancer, as well as aging.
