Darts supremo Michael van Gerwen says the serious back injury plaguing his career came as a result of showering with his wife.
The world number one, arguably the sport's finest ever player behind the legendary Phil Taylor, was hit by the old injury at last month's PDC World Cup.
Thatinitially put his place in the World Championships, which begin in London this week, in doubt.
The injury dates from 2017 and van Gerwen has finally explained how it originally happened - and his wife Daphne Govers was involved.
"I didn't slip in the shower. I coughed," the Dutchman said.
"The doctors don't know what has caused it. It could happen to anyone they say.
"The most important thing was my lung and heart were okay."
There will be a restricted world championships crowd of 1000 spectators at Alexandra Palace on Tuesday although they will then be excluded when London goes into a Tier 3 until December 23.
The 31-year-old van Gerwen lost the last world final to world number two Peter Wright, the Scot who has had trouble nailing titles throughout his career.
Van Gerwen will be the favourite again but has struggled during lockdown without the adrenaline rush the normally boisterous and packed arenas provide
"It's different for everyone but you have players who don't mind playing in front of no crowds," he said.
"I do mind. I'm a stage player. If crowds are against me or back me – I don't care. I want to perform for them, give it a go.
"The adrenaline in my body pumps up. I don't have that now."
