After thirty, a body has a mind of its own.
As you age, feelings do diminish.
From the age of 14 until I was 50, I just got on a treadmill and ran. I never stopped to assess what I was doing or to pat myself on the back.
People put barriers up in your path, and one of those barriers is age. They tell you, "You're too old. You don't photograph so well anymore." I know I don't photograph so well anymore, so what can I do? I can do something different, where it doesn't matter as much how I look.
It is true that in this culture, they throw you out when you get older. I see it all the time, especially in my business. At my age, you're playing somebody's mother - and there aren't even a lot of those roles!
