Sir Bruce Forsyth believes he is living "on borrowed time" and says the relentless schedule of Strictly Come Dancing "can drag you down".
But despite feeling his age, the 85-year-old TV presenter, who first appeared on Sunday Night At The London Palladium in 1958, said he would not be retiring just yet, even if the hit BBC show might not be part of his long-term future.
Sir Bruce told The Sun (£): "The constant week-after-week can drag you down, especially when you are getting older."
"I know I'm on borrowed time. There's no getting away from it. When I look at all my friends that have gone - Eric Sykes, Frankie Howerd, Sammy Davis Jr - I know I'm on borrowed time".
