He's had to give up his full-time job as a chef about 3 years ago, when he felt the physical toll of full-time work while battling cancer, was getting too much.
"It just got to the point where I couldn't do it," he said,
"I was getting too tired, all of the time."
It was a necessary break, but Kerry said the excess of down time drove him "up the wall".
So, he decided to take on a part-time gig running a coffee cart. He gets up at 5.30 and plants his coffee cart out on the road.

Kerry was determined to live his life as normally as possible - rather than letting his illness dictate his life.
"I've seen too many people in hospital, lying there waiting for the day to come.
"They might get told they have six months to live, and it's like they put a circle on the calendar and that's what they aim for.
