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: "I've got three one-man show dates fixed for next year and I'm doing another thing for TV in April that I can't talk about yet. So if I was to leave Strictly Come Dancing, I wouldn't retire. That's the furthest thing from my mind at the moment. While I'm able to walk and play golf I'll still work."
Sir Bruce admitted the punishing schedule for Strictly was difficult for him, despite him having a break during the run, saying: "The constant week-after-week can drag you down, especially when you are getting older."
On the dancefloor former England rugby international Ben Cohen has said playing in a World Cup final was easier than taking part in Strictly.
The 35-year-old was booted into touch after failing to out-tackle actor Mark Benton in last night's dance-off.
Cohen and his partner Kristina Rihanoff racked up just 27 points on Saturday – the lowest score of the night.
