Russian PM Vladimir Putin has joked that he and his Italian counterpart Silvio Berlusconi could stay in their jobs until the age of 120.
Mr Putin was responding to Mr Berlusconi’s offer at an informal meeting in Russia to help fund research into extending the average lifespan.
Mr Berlusconi pointed out that it could be difficult to remain in a job with such a heavy workload for so long.
He said he had not managed to take a single day of holiday all year.
