The TU Delft Geron project was a national study in which 750 subjects, who lived independently, were assessed. In total about 80 variables, all more or less important for product use, were measured. The sample consisted of four age groups ranging from 50 to over 80 years of age; a group of young people (20 - 30 years) was also studied for the purpose of comparison (see DINED 2004 table). Women and men participated in about equal numbers. (1998)
