Better metaphor than "As old as the hills"?

I'm surprised nobody has mentioned "as old as time itself" yet.

Since the invention of payment... as old as the bills.

As old as a Kwik-E-Mart sandwich.

Apropos of today, I'm so old I voted for Richard Nixon!

I was too young to not vote for Nixon. I almost voted for Carter, but I was a couple of months shy of 18 for the 1976 election.

I think my personal favorite weird thing about my age is that the draft ended (1973) before I turned 18, but the Selective Service registration didn't start till 1980 and I was too old for it by then (you had to have been born after 1960). I was in this couple of year window between those two.
