How do I handle a long gap on my résumé? after 7 years as a machine operator

My résumé shows a gap from a layoff and some health issues. I would rather hear the honest version than the polite one. I am not sure how much to explain. How did you handle it on your résumé?

I listed the volunteering and course under the same dates and kept the explanation to a sentence in the cover letter.

A short, honest line such as 'family caregiving' is enough for most employers. They mostly want to know you are ready now.
