Yep, I took buyout in 2007 at 57. Had another job offer but turned it down because I followed someone advise many years earlier: obtain and have many sources of income before you even think of retiring. I sometime wish I had taken that other job offer and worked another year or two. Because we all know what happen in 2008!!! I lost a lot of money during that time, but I never regretted retiring. Just meant that I wasn't going to buy that $100K+ RV. But I have traveled the world since.
Now, if NLST comes through that $100K RV could still be in play :-) Although I may be too old to drive it.
