Being an old father will help your child live longer.

For fathers, having children later in life may increase the length of their children's telomeres (the end pieces of DNA in chromosomes) and help increase their lifespan.

Children of older fathers may live longer.

Researchers at Northwestern University (USA) measured the length of the DNA telomere in the blood of 1,779 young people inPhilippinesover 30 years and consider the age of their father and grandfather at the time of their child's birth.

The study found that the telomere length of the study participants increased in direct proportion to the age of their fathers and grandfathers at the time of their children’s birth. Each year that fathers delayed fathering children increased the length of their telomeres. This lengthening was roughly equivalent to the annual shortening seen in middle-aged chromosomes.

The discovery was published in the Proceedings of the National Academy of Sciences. The telomere is considered a “chromosomal clock” because it is central to the phenomenon of aging in humans. According to anthropologist Chris Kuzawa at Northwestern University, telomeres shorten over time in almost all cells, except sperm. Thus, longer telomeres are a sign of biological youth and health in humans.

A previous study found that people with shorter telomeres were three times more likely to die from heart disease than those with normal telomeres.
