Results were derived from a questionnaire completed by 189 seniors enrolled in universities for seniors. 68.1 % defined themselves as Internet users. The seniors asked principally go online to check e-mail and gather information. They state that the Internet is useful, helps them to stay up-to-date, and to preserve (but not expand) relationships. Non-user status is not attributed to old age or health reasons. According to the technology acceptance model, ease of use and perception of utility were related to both Internet use and its intensity of use. Family influence also played a key role. Gender differences were not found in Internet use, intensity of use, or in use motivations.
