Birthdays with a zero at the end of them are usually thought of as life-stage benchmarks, especially when you hit 30, 40, 50 and 60. Someone I work with--who may or may not be named Polly Wogg--recently turned 40 and probably experienced a few of the following.

Here are a few samples from a long CafeMom.com list.

--You sort of stop caring about the grays. You convince yourself they are cool.
--Five years ago felt like yesterday.
--You can't drink as much booze. Well, you can. But you pay for it dearly the next day.
--When some fool asks for your ID it's the best day of the year and you tell everyone you know that you got carded.
--Country music starts to sound cooler.
--Strange and very long hairs suddenly appear on your chin.  And in other weird areas.
--You realize 40 isn't THAT old.
