Can somebody please tell me what deifintion we are using for "deadzoner?"

Somebody called me a "deadzoner" the other day and I told them "I was not." Yeah am over 50, but If I make it to 65, with pretty conservative assumptions, I will be about where I was with the DB without having to draw down the 401k balance. If I draw down the balance to age 90, I will be way ahead.

That being said, markets crash and recessions happen which could affect the assumptions, but annunities and DB's are not immune either as we have seen at least once in our career..

Anyway, so what is the definition of a deadzoner?
