"The Burma Bridge consists of a bottom cable, which you walk on;"

the cable is connected by ropes to two cables about 1.2m higher up.

These two cables are the ‘hand rails’. Of course you also wear a harness, which is connected to a cable above your head. Even the slightest breeze has you wobbling precariously over to one side.

"The famous words “don’t look down” "

are totally negated here as you have to concentrate on placing your feet neatly on the bottom cable,

while staring wide-eyed down at the potential plunge. Even though you know that you can’t fall because you are strapped in and connected to the top cable.
