that is the point. everything when we do it in a tired position will produce bad results, because our body and brain are forced to be able to do activities when at that time we should be able to rest and not do any activities. because many gamblers force themselves to gamble even though they are tired all day doing that, and in the end they lose a lot because the decisions they take are very bad since their brains are unable to process gambling at that time.
No matters what we do, if we are tired, we can't gets what we wants and we can only see the bad results. That will makes us sad and sometimes we can't accepts what we gets but that's the risks for us if we don't realizes if we are tired. When we activity, our body and brain can feels tired and if we don't take a rest, we can continue doing that activity. If we still do that activity, we can't focus and that can makes the bad results. When we wants to playing gambling, we must make sure that we are not tired because that can makes us lose focus playing gambling and will angry if we lose the money. That can makes our emotion becomes high and will keeps playing gambling but that's not recommended as that can makes us use more money which can gives more losses.
