Bestselling author Warren Macdonald will round out the GBA 2019 Annual Meeting with his closing session on "The Power of Perception," challenging you to change the way you see. Macdonald's survival story began in April 1997 when, climbing to the tallest peak on Australia's Hinchinbrook Island, he became trapped beneath a one-ton boulder in a freak rock fall. Two days later he was rescued, only to undergo the amputation of both legs at mid-thigh. In 2003, he became the first double above-knee amputee to reach the summit of Africa’s tallest peak, Mt Kilimanjaro. Check out his inspiring video message for everyone attending the Annual Meeting.
