79 is the new 69. We live in such an active community that keeps us young. We take better care of ourselves and have better healthcare. We look better. Maybe it keeps the age discriminators at bay.
I don't feel any age prejudice (I'm 71, the new 61

), but we are living with a mostly like-age group. I haven't spent much time in large, busy age-diverse cities lately. Maybe it would be different there. People rushing down the sidewalk to get to work, jockeying for seats on buses & metros... that kind of thing.
I do miss being in a mixed-age group sometimes, but I think TV is the right place to "age out," and I for one haven't experienced any age prejudice.
