RTE sports star Michael Lyster has turned to cycling after he was diagnosed with potentially fatal heart trouble.
The presenter of The Sunday Game revealed just how close he was to death when he went to visit his doctor.
Michael (55) said: "He told me 'You are in heart failure. It is exactly what it says it is, the heart is failing'," he told Matt Cooper on Today FM's The Last Word.
"It is not like a sudden heart attack, my heart was just giving up.
"I had 15pc of heart function.
"The next stop after that would have been the church in Cabinteely."
The GAA frontman lost 2.5 stone, but he said that he has responded so well to medication that surgery isn't on the cards.
He has been told of different kinds of scenarios including a heart transplant and a bypass, but medics have managed to stabilise his heart function.
"I wouldn't have been bad but I'd have a cup of tea in the morning and it might get to 3pm and I'd realise I had no breakfast and lunch. I was definitely spending too much time in the pub and I wasn't getting enough exercise," he admitted.
Michael was on Matt Cooper's The Last Word with presenter Sile Seoige to discuss returning to physical fitness after illness.
And Michael said that it has been a gradual return to exercise, which at first left him very tired.
"Now that I'm down to under 14 stone, it is a case of keeping it down," he added.
