I retired at 69. It was partially due to financial considerations but a key driver was that I liked my work. My biggest problem was that between work and personal time, I was overbooked. So much so that I resented any additional demands on my time. But having it to do over, I wouldn't do anything different.
My wife retired from her business three months after me at 55. The following year, we spent 6 weeks in Europe. However, my health at 76 is nowhere like what it was twenty or even ten years ago. Things that I would have done at 65 are out of the question now. I no longer consider any foreign travel. Even an overnight is a struggle now.
Nobody wants to spend the last years of their life eating pet food or working as a greeter at Walmart for minimum wage but there is a huge range between that and having more money than you will ever need. Each of us has to strike a balance that works for us.
