When Did I Get So Old?

For some reason, AARP seems to think that I'm over 50. I get mail from them every week with exciting details about what's offered to me for simply being over 50. I've called them. I've sent notes in the business reply envelopes stating that I am 28 years old, but still they persist. Did my parents lie about my year of birth? Was I born in 1957, when my parents were 2 and 3 years old? It makes me so sad to think about the waste of paper and of postage - hey, we will need those trees when the ozone is shot, and we will need that money to put towards our social security when it's all depleted in another 50 years!!!
