eh. now that people have B funds and 401k's, and in the event of BK that money is yours to keep, you wont see people desparate to stay til 70 because they lost their pensions, like what happened this past decade. Those of us who are coming into the industry knowing we don't have a pension, but instead have defined contributions, will hopefully be able to escape by age 60 to 65. If you want to fly to 70 "for the fun of it," well, that's great. but essentially it would be like working for free, and then dying. haha.
