I learned something new about myself today: I suck at guessing people's age. It first became clear when I went to lunch with my boyfriend and one of his co-workers. I pegged the co-worker as mid to late twenties, so you can imagine my shock when he mentioned his high school prom -- in 1986!

Further proof: I took this quiz, which shows pictures of women and lets you guess their age, and I only got two correct! Pretty pathetic, although I challenge anyone to get a perfect score.

Think you're a good judge of age? Prove it by taking the quiz yourself. But I warn you, with all the miracle-performing anti-aging products out there (and in contrast, all the ugly things that can damage your skin), it's not as easy to guess as you might think.

Good luck!
