People do many things to raise money for charity. The latest crazy stunt
came from an English man who decided to push a Brussels sprout up the
highest mountain in Wales – with his nose. He wanted to raise $8,500 for a
cancer charity. Stuart Kettell, 49, said he loves challenges and will try to do
anything for charity. His other challenges include walking 800 kilometers on
stilts and sitting in a box for a week. He said: “I have seen first hand the
amazing work [the charity] Macmillan Cancer Support does, not only for the
patient but their family and friends too.” He added: "People's cancer stories
inspire me even more to carry on, and my challenges are going to get even
more crazy."
It took Mr. Kettell three days to push the Brussels sprout up the 1,085 m-
high Mount Snowden. He wore a specially designed face masks so he
wouldn't scrape the skin off his face. He practiced for his charity mission by
pushing a Brussels sprout around his garden. He chose a large sprout for his
Snowden challenge. It was about the size of a table-tennis ball. He said he
wanted a larger one because it would not fall down a crack. He spent three
days on his hands and knees with his nose a centimeter or two above the
ground. He told reporters there was “a huge amount of pain” in his knees,
wrists and back. He said he was happy because his training worked, he
reached the summit, and he raised money for the charity.
