The veteran adventurer Sir Ranulph Fiennes says there is no reason for him to stop going on further expeditions.
He made the comment after being forced to abandon his latest polar trip because of frostbite.
At the age of 68, he had been training to walk across Antarctica in winter - something never been attempted before.
He was speaking to Andrew Harding.
