In 1986 , a New Zealander Hackett popularized Bungee as a commercialized sport of mass entertainment . This sport is very challenging . It is a test of people's psychological ability of endurance . Especially when descending , as if they are watching a fast forward tape and when they bounce back , they sway around . The timid people will shrink back at the sight of it . Even if they jump off , they find it hard to avoid screaming with closed eyes . No wonder people give the title ' brave ' to anyone who jumps off .   You see , the bungee participants take a deep breath when they stand at the starting spot and then , like diving , their heads are over heels and they jump off into the realm of the combination of heaven and earth . The wind roars at their ears and their bodies rapidly descend . They do not even have enough time to do several gymnastic movements and they are rebounded to the upper air by the cord .
