Supposedly: Children with older fathers and grandfathers 'live longer' (http://news.ycombinator.com/item?id=4152379 http://news.ycombinator.com/item?id=4152379)
"Experts have known for some time that lifespan is linked to the length of structures known as telomeres that sit at the end of the chromosomes that house our genetic code, DNA. Generally, a shorter telomere length means a shorter life expectancy. ... However, scientists have discovered that in sperm, telomeres lengthen with age."
- Dn_Ab 14y agoCausal links cannot be drawn with that paper. This study was unique in showing that telomere length determination by paternal age was generationally additive. It was not designed to determine if older paternal age translates into longer lifespan.
