Paid everything off at 40. Wife has a 401k. I have a small 401k and will receive a pension in 5 years. At that time, I'll also be able to keep my insurance. We also have IRAs, Roth IRAs, land, and mutual funds, all of which we add to monthly. We live off my wife's income. I haven't spent any of mine in years. That's about as prepared as I know how to be, except I'm contemplating building a rental house of two for an additional income stream.
