In your shoes, I would jump at the chance to retire a year and a half early. However, everyone is different. I spent years dreaming of the day I would retire, and had all sorts of hobbies/activities/volunteer stuff lined up when that day came (and couldn't wait to spend more time doing them). I retired 8 months ago, at age 54 years, 7 months, and have not regretted it one bit. I'm busy every day (doing things I enjoy), and can't imagine trying to fit "work" back into my life anymore. You only live so long........think about what you really want to do with the time you have left, and go for it.
