In 2017 the number of people aged 60 and over has reached one billion, and will reach 2.1 billion by 2050 (UN, 2017). In Brazil we add that we are aging fast. Between 1940 and 2017 (IBGE, 2018), we started to live 30 years more. In this scenario and under the Design view, this thesis seeks to contribute to longevity with quality, from university extension services. To do so, the following thematic axes were investigated and correlated: the 50 public (the age range corresponding to the transition between working life and retirement); senior entrepreneurship (including social entrepreneurship, self-entrepreneurship, and intrapreneurship) and university extension (a concept that is re- peatedly revised in extension pro-rector forums). The methodological course was established from my performance in the Continuing Education Program PUC-Rio mais de 50 and was based on the Design of Services and participatory methods, participant observation and free association of words. This work was guided by Emotional Design and resulted in the Programa de Iniciação Científica e Tecnológica Sênior da PUC-Rio (PICT Senior), characterized by 50 participation in research groups at the PUC-Rio. This replicable service was created with the collaboration of research professors from various university departments, among others and support of the Coordination of Scientific Initiation; Central Extension Coordination; ViceDean of Development and Human Resources. The first prototype, carried out from October 2017 to September 2018, served six 50, and the second, scheduled to end in January 2020, met the same number of participants. The PICT Senior was a new way for the 50 audience, giving them a role of collaborator and entrepreneur of life itself, confirming the university as a space to promote longevity with quality.
