I only know a handful of Witnesses, but I do know several ex-Witnesses. All of them left in their late teens, which (as I've read here) is pretty common. I know there are a lot of people here who left later in life. So out of curiosity - how old were you when you broke free (became inactive, DF'ed, DA'ed, etc.)?
Have a happy Wednesday.

Edited to add:
My hubby was baptised at 11, stopped believing by 16, and was inactive by 20.
