For Edward Nathan a heart attack proved not the end, but the beginning of a whole new chapter in his life.
The Rotorua 55-year-old credits a heart attack in 2011, combined with a knee replacement, with transforming his lifestyle from a "hedonistic" one into a healthy lifestyle that has a strong focus on fitness and well-being.
Now he's sharing his story as part of Heart Week, which ends Sunday.
While there was a strong family history of men dying of heart attacks on his father's side, Mr Nathan said it wasn't until late 2011 - when he had his second heart attack - that he had a wake-up call.
He'd had one 10 years earlier. It prompted him to quit smoking, but because it was able to be controlled with medication Mr Nathan said he was able to push it out of his mind to some degree.
