Sir Chris Bonington, 80 years old this week, is one of Britain's most outstanding climbers and mountaineers and today's Friday Night Video is a short interview with the man himself, shot at the National Geographic Society earlier this year for The Creative Grid.

Berghaus announced earlier in the week:

"Very recently, Sir Chris lost his wife Wendy to motor neurone disease (MND) and will use his 80th as an opportunity to improve awareness of the condition, for which there is no cure and about which very little is known. He and his family are also raising funds online for three organisations, including the Motor Neurone Disease Association, which funds research into MND and provides support, along with Hospice at Home and Cumbria Crossroads, which both gave care and support to the family during Wendy's illness."
