Year off after the nest is empty?

My kids are starting to get older and I was pondering a question in my head recently. Would it be OK to take a year off once the last kid is in college (or even when the last kid can drive)?

Basically, any parent knows, raising kids takes a lot of responsibility and at some point, I’m going to need a break from all of it. I might not be able to retire until 65+ but I could swing a year off from work at 50ish and minimize my expenses. Basically I would take up some serious hobbies that would take a lot of my time but not yield any significant income. Do you think it’s worth it, for my mental health?

This is just a thought, I haven’t discussed this with my wife, it’s also a few years out still.
