The finding was first noticed in 2001. Researchers from the University of Toronto studied 1,649 Oscar-nominated actors and actresses. When they accounted for factors that could influence death rates, they found that among the participants, Oscar winners had a survival advantage of about four extra years of life, and actors who won multiple Oscars had an advantage of six years. Nominees who didn’t win had the same survival rates as their non-nominated peers.
Success could possibly account for the survival advantage, the researchers say. They speculate that since stars are subjected to intense personal scrutiny, they pay special attention to their looks and behaviors. Consequently, they may avoid risky behavior and focus more intensively on eating and exercise. Not to mention, many have the means to hire nannies, trainers, and managers, which could mean they are under less stress than the general population.
