Having less number of children and, that too, later in life, may help you live longer, a new study on birds has found.

New research into ageing processes, based on modern genetic techniques, confirms theoretical expectations about the correlation between reproduction and lifespan.

According to the study on birds by the University of Gothenburg, Sweden, those that have offspring later in life and have fewer broods live longer. And the decisive factor is telomeres. Telomeres are the protective caps at the end of chromosomes. Their length influences how long you live.
