He may not have fully functioning legs, but there's no mountain high enough to keep 49-year-old David Lim from climbing Mount Kinabalu for charity.

A veteran Everest mountaineer who has already scaled Kinabalu eight times, Mr Lim will on Friday attempt to reach Kinabalu's 4,095m summit in one day to solicit donations for the Society of the Physically Disabled (SPD). Most climbers usually take two to three days to complete the climb.

"I see it as climbing for those who can't," said Mr Lim, who has personally donated $4,095 to his own cause and hopes to get more people on board.

Mr Lim, whose legs are partially disabled due to a rare nerve disorder, will be the first mobility impaired person to climb Kinabalu in a day if he succeeds.

All donations - 100 per cent of it - go directly to SPD.
