The subjects’ mean age was 68.8 years (SD = 3.02), with 59.9% (121 subjects) aged
between 65 and 69 years. Of 202 subjects, 57.9% (117) were women and 84.7% (171)
had received a standard education. Homogeneity was confirmed between the two
groups, as there were no statistically significant intergroup differences in age, sex, or
experience of a standard education.
