I for one hope to retire at 59. I have no desire to keep working in ever deteriorating conditions. I'd like to enjoy my pension and do things I'm not able to do now because of time-constraints. Not when I'm in a wheel-chair for all intent and purposes.
Why can't this be decided on on case by case basis. Why does it have to be black and white? Heck, I should be able to retire by 40 if I choose to do so...
