If your B plan accrued $1.6 million, as was stated in the original analysis, and it has already been stated that $130K alone for life isn't enough, how could you go some time without having to touch any of the $2.4 million. With aggressive investing after retirement, how can you be sure that you won't lose money? The market was flat for 11 years, what's to say that won't happen again?
I have other assets. It's possible I wouldn't have to touch it at all, so may as well go aggressive if it's in there for the long haul.
I'm not really interested in encouraging people to go past age 60, and don't intend to myself, but from the looks of it, most everyone is going close to the max anyways.
