I beg your pardon, Jacqueline. I happen to be 21, and I have been for many years. My profile shows the year my birth certificate was issued, which was a long time before I was born - it so happens that I was pre-conceived. I was born in 1994 and next year I will be born in 1995. The secret to life is to find the right age and just stick with it ... except when in stores on days that they give senior citizen discounts, of course.
Besides, when you've been 21 this long, they say the memory starts to go. It is so much easier to remember my age when it doesn't keep changing every yer.
