We retired at the end of 2011. My wife was 61 and I was 64. Both of us had good jobs, but finally burned out with the ever-increasing work loads.
We're doing well financially with multiple income sources. Our portfolio continues to grow, despite the monthly draws. Our net retirement income is 50% higher than our net working income. I didn't expect it to turn out that well, but I guess years of saving, living within our means and being debt-free finally came to fruition.
Having said that, retirement isn't much if your health goes to pot. I'm doing well, but my dear wife of 54 years has dementia. It didn't become clear to me until about 5 years ago, but now that I have figured it out, I can trace the early symptoms back 14 years. It is what it is.
