That's true. Also, a lot of porn actresses commit suicide.

A lot of people commit suicide. Not just porn actresses. However, I know of three right off hand (well two acresses, and one actor). The most famous was Savannah. Then there was Cal Jammer, husband of Jill Kelly. And Shauna Grant. I can think of three other actresses off hand who also killed themselves, but I can't remember their names.
However, in all cases, these were people who had trashed their lives not just with porn, but with drugs (Savannah dated Greg Alman while he was a heavy heroin user).
