About 10 years ago I used to say:
I look like 42, I am 32, I feel like 22 and I behave like 12.
Now I feel like 52, look the part, am 42 and still behave like 12 (sometimes).
Pete, I am no young thing either, but you look indeed quite fresh for your age. I have put on quite more wrinkles than you (don't mind them though).
