Amputation of all four limbs was necessary to save Andrew's life from septic shock. After he recovered from the surgery, he spent several months in rehabilitation. After his first walk (with no hands or feet) up Blackford Hill Andrew took part in skiing, snowboarding, paragliding, orienteering, running, hill walking, caving, rock climbing and mountaineering. He has walked up Ben Nevis, raising £15,000 for charity in the process, run the London Marathon in 2001 raising £22,000 for charity, made many ascents of 4,000 m peaks in the Alps and climbed Kilimanjaro with three other disabled mountaineers raising £5,000 for charity. In 2012 Andrew climbed the Olympic Stadium of the London 2012 games as part of Channel 4's "Meet the Superhumans" campaign to launch the Paralympic Games.
