If you are planning a bungee jump, you should check if the personnel supervising the jump are experienced. The bungee site should be free of any obstacle that may create a problem during the jump. First-aid and rescue equipment should be availabl. But before you take the big jump, first consult your doctor to see if you are physically fit enough. And at the last moment, if you think that you do not have the courage to jump, tell this to the people handling your jump. Don't go on with the jump and put yourself in even more danger.
