Pete12344 is up there in the age column, and I know he's not going to stop playing! In fact, I think he competes in a double digit amount of leagues each year.
Not that this is a bad thing, but when you get to an advanced age, it is a good way to pass time because you might not be able to do all the other stuff you used to.
So to answer the question, if you love fantasy football and have a computer, you probably will never stop.
