hmmm...in my case, it did actually make me do some deep thinking on what "old" was.
Until that point I was still of the mind that whether someone was 60, or 90, they were still just as old as the other.
I mean, what possibly could have happened to them in that 30 year difference?
I was only about 3/4's of my way to 30 at that time, and it really gave me pause.
