I wish I could do that when I am your age

Do you ever realize how "passive aggressive" phrases that end in "... when I'm your age!"  It's like, "what you just did means nothing to me, except that you did it when you're excruciatingly old."  I was watching "Oddities" on the Science Channel, and one of the hosts said something like that when an 80-something contortionist twisted herself into a pretzel.  I couldn't do it in my current age... in fact, I could never do it.
