The U2 frontman has revealed a near-death encounter inspired the band's hotly-anticipated new album Songs of Experience.
In a candid interview with Rolling Stone magazine, Bono — real name Paul David Hewson — referred to the incident as an "extinction event".
And while he admitted the health scare was physical in nature, the 57-year-old declined to give any exact details on what threatened to take his life.
Explaining his outlook, the Dublin-born star said: "People have these extinction events in their lives — it could be psychological or it could be physical.

"And, yes, it was physical for me, but I think I have spared myself all that soap opera."
Revealing he wants to leave fans to reach their own conclusions, Bono continued: "Especially with this kind of celebrity obsession with the minutiae of peoples' lives - I have got out of that...
"I want to speak about the issue in a way that lets people fill in the blanks of what they have been through, you know?"
Despite the scary experience, the City Of Blinding Lights singer — who cites mortality as an influence on his latest music — is aware of his privileged position.

Detailing his approach to life, he mused: "I am the f***** luckiest man on Earth. I didn't think that I had a fear of a fast exit."
Bono's U2 bandmate The Edge — real name David Howell Evan — has also spoken of the frontman's dice with death.
Making sure to protect his friend's privacy, the 56-year-old told Rolling Stone last month: "He [Bono] definitely had a serious moment, which caused him to reflect on a lot of things.

"But where that brought him to as a writer was an amazing place."
This isn't the first time Bono's health has been a cause of concern, with the main main describing his scares as "shocks to the system".
In 2000, the celebrated talent was tested for throat cancer by a specialist.
Luckily, much to the relief of the singer and his worldwide fanbase, the scare turned out to be a false alarm.
