Although it is always interesting to engage as many people in clubs, associations and groups engaged in outdoor activities, the selection of candidates is a necessity.
Never finished know ourselves, so it is impossible to predict in all cases how we will behave in the future, particularly in completely new situations, difficult, risky or extreme. In other words, how we behave in front of a survival situation? The question can not be answered in all cases and this is a problem for the leader of any group engaged in outdoor activities, it can have no certainty that the people under their responsibility will react properly in such cases . For mountain guides, tours, etc.. this is part of the job because rarely could or should select participants for their trips if they depend on such work to live. That is, rarely reject a client or restrictions will be imposed unless there are laws or regulations in this regard. But in other cases it is possible to take some action.
