A cancer survivor from Wickham, in Hampshire, is to row across the Indian Ocean for charity.
Ashley Wilson, 36, is also epileptic and suffers around one seizure a week.
There is a good chance one will strike while he is thousands of miles out at sea but the Scout leader, of Dixon Park, Wickham, is unfazed.
“Nothing will happen really. I would bounce around the boat but it would probably do much less damage than if I had one at home. I have lived with it for so long now that it’s part of my life,” he said.
Mr Wilson was at the Co-op in Wickham to boost awareness for his campaign with a 12-hour indoor row.
His efforts will raise money for the Young Epilepsy Charity, The Scout Association Charity, and Macmillan Cancer Support.
On his voyage will be joined by fulltime adventurer James Ketchell. Mr Wilson said: “He will effectively be my carer for the duration of the row and he will get a lot of training from the Young Epilepsy society. It’s probably more daunting for James, looking after me, than it is for me.”
The pair will attempt to row 3,600 miles across the Indian Ocean in a world record time, setting off in April 2015.
