People do often think only of the based number systems.. binary, base-3, etc. Fact is, you can define any number system you want to. You can define a number system in which 1 is the same as any other number.

We are only limited by our imaginations.

It's older than that. Been around since Adam was a pup.
I suspect its utterance at any Australian airport might get you the rubber glove treatment for telling jokes way past their use by date.:D

How about this answer: "0.... in Plutonian years."

Actually, I like that. I think I'm going to try it if they ask.

I find this kind of interesting since I will be having a connecting flight out of CLE over to ORD in June. I hope they stop this foolishness cause in the mornings I am not one of the friendly ones. Plus with me I am 30 but because of genetics I can still pass for my mid 20's. :p

good thing alec baldwin probably doesn't travel commercial. if they asked him that about his kid, he'd be in jail for child kidnapping ... ;)

IDs Without Birthdates?
 

I just checked and the two IDs I have for a couple of US Government agencies contain the agency name, a picture, and an expiration date -- no birthdate or address. Since I need one or both of them when I travel, I have them with me anyway. As much as I like to be as low-key as possible when I fly, one of these may become my ID of choice if the "state your age" disease spreads.

My retired military ID card, which I have used on occasion, has no expiration date.

Bouncers
 

As TMOliver pointed out several pages back, this is an often used method for checking to see if you're using your real ID or someone else's. In my town (Boulder - college town) bouncers routinely ask for your height, eye color, birthdate, etc, just to see if it matches what's on the ID you just handed them.

I always thought it was funny that it is much harder to get into a bar in Boulder Colorado with a fake ID than it would be to get by airport security. Maybe the TSA has finally realized this?
