I'm not old, and I'm not getting old.
Despite certain physiological and hormonal changes, I generally wake up feeling like I did when I was 27. And as long as I wake up feeling that good, age is just a number -- one that I choose to ignore.
I'll be 55 next month. Thanks to a refusal to acknowledge my age, and good genes, I neither feel it nor look it. I intend to leverage that as long as possible.
YMMV.
