I retired at 59 1/2 with no regrets. I had been at a job with the same company for 37 years. It was a good job, but it had a lot of built-in stress. You definitely have to weigh your options and make decisions when you retire. For us, moving to a warm climate was a must. It also helps that we chose an area where the cost of living is significantly lower than the New York metropolitan area (that wasn't hard to find). We live better here on a pension than in New York on full salary. Some thought needs to be given to moving away from family, but most of mine had already left the hometown area.
Keeping busy after retirement is very important, so we chose a place where we both had plenty to do (living an hour away from WDW isn't bad, either). My wife has multiple theater groups she stays active with and I play with about 8 bands, a few community-type and most pro (money to spend at WDW).
Being at the leading edge of the baby-boomers put me in the right position to retire, too, at least financially. I understand younger generations have a lot more planning to do, which is good in any circumstance. A mistake many people make is thinking retirement is so far off, if not impossible, they don't plan for it or at least don't start planning as soon as they should. II know it's easier said than done, but don't make assumtions about retirement, make it happen.
