The contemplation of volunteerism as activity in medical school, put forward by Sapiro and Mattiello in the present issue of Scientia Medica, brings to light the idea that those who provide benefits have to understand why they do so, as occurs among adults. And to understand selflessness, a topic that has been recurrent in medicine over time, reading about what has already been produced is not enough, since exposure to the practice of concern for the welfare of others is essential. Observational evidence suggests that volunteerism may be beneficial to the mental health and survival of exposed individuals, even though the causal mechanisms remain unknown. Consequently, further studies are needed to shed more light upon the topic, but while that does not occur, the following quotation gives us some food for thought: "If you would like to be selfish, you should do it in a very intelligent way. The stupid way to be selfish is ... seeking happiness for ourselves alone ... the intelligent way to be selfish is to work for the welfare of others." The Dalai Lama.
