To me elderly is 90+ . I don't think of myself (62) as elderly or a senior citizen. Most of my age group will live to be in their 90's and that's a long time to be considered elderly
At the fair last year I had a guy guess my age and he guessed 54. He was speechless for a second and then said I had good genes and took good care of myself. I laughed and gave him a big hug and got my prize. Although I have gray hair, some wrinkle and a 62 yr. old body I think I look and seem younger because I am happy, cheerful, energetic and positive.
