Why do some people live for longer than others? The genes in our DNA sequence are important, helping avoid disease or maintain general health, but differences in our genome sequence alone explain less than 30% of the natural variance of human life expectancy.

The study traced the primary source of this variation to changes in the mRNA content in germline cells and somatic cells . The mRNA balance between the two types of cells is disrupted, or 'decouples', over time, causing ageing to run faster in some individuals than others. The findings are published today in the journal Cell.
"Whether a worm lives to day 8 or day 20 is down to seemingly random differences in the activity of these genes. Some worms appear to be simply lucky, in that they have the right mix of genes activated at the right time," says Dr. Matthias Eder, first author of the paper and researcher at the Centre for Genomic Regulation.
