How long have you had your chap stick/lip balm?

I took mine out the other day for the first time in months and realized that I have had the same Chap Stick for 3 years! I rarely need it now since I'm no longer living in the desert but even back then, I kept myself hydrated enough that my lips didn't get dry and chapped. Do you go through many sticks/jars of lip balm or are you a rare user? How long have you had your oldest stick or jar of lip balm/Chap Stick? Another question: do you favor the flavored type or the plain type?
