Religiosity represents one of the most valorized personal realities of humans. The purpose of this research is to find the peoples’ perspective on their own Religiosity. The main objective was to identify the most important benefits and the biggest cost or sacrifice that believers perceive in performing in a religious way. A descriptive, cross-sectional study was conducted, based on a quantitative questionnaire, with face-to-face directly collected answers, applied on high-school students. The results were analyzed using Microsoft Excel application. The conclusions reveal that religiosity is seen as a practice with benefits rather at a personal level, than a social or transcendental level.
