For the 5th time, the annual Mexican Health and Aging Study (MHAS/ENASEM) seminar for users of the data was organized in collaboration with the Mexican National Institute of Geriatrics (Instituto Nacional de Geriatría, INGER). The workshop had 107 registered attendees and was held for the first time virtually, 28-30 October. There were 25 oral presentations (by 15 established researchers and 10 students) plus 5 small group discussions. A trademark of this meeting is the time devoted for questions and answers. Thirty institutions were represented, including 15 from Mexico and 15 from US, Canada, Netherlands, and Cuba.
