Wil,
Despite the fact that I'll be 66 tomorrow and therefore can qualify for my full Social Security, the current plan is to work until the end of 2015 (my wife is already collecting her Social Security since she's older than I am and retired 6 years ago). After all, my job pays well and there's no heavy lifting ;-) Besides, for each year you delay past 66, your Social Security payments permanently increase by 8%.
Note that I'm already collecting two defined-benefit pensions (I had no choice since at 65 is was take it leave it, that's what it means when they say it's a DEFINED-benefit pension) and I have a 3rd one that I can delay until I'm 70 1/2 which continues to grow in value at a minimum rate of 5% per year. And the wife and I still have our 401k's and the equity in our house which is about 70% of the current market value.
Besides, we're still responsible for the care of my wife's 88 year old mother (this is why she was forced to retire 6 years ago when her mother had a stroke and couldn't be left alone) so that really prevents us from doing any traveling together so I might as well continue to work until our situation changes, but whatever, I'm done in 853 days (I have a countdown app on my iPhone).
