It becomes very difficult to control yourself in any exciting situation especially any kind of sports competition or gambling and casino. If you are holding a bet in any kind of situation, your nervous weakness will work and you will not be able to keep yourself steady. Let's say I bet $400 on sportsbetting, this $400 bet will surely trigger my nervous breakdown during the match and I will never be able to steady myself. Just as this is true for me, the same action will work for all other gamblers.
