That is roughly double what prior research concluded, and it mirrors the findings of lifespan studies in laboratory animals.
"Lifespan is undoubtedly shaped by many factors, including lifestyle, genes and, importantly, randomness - take for example genetically identical organisms raised in similar environments that die at different times," said Ben Shenhar, a doctoral student in physics at the Weizmann Institute of Science in Israel and lead author of the study published on Thursday in the journal Science.
