How do I handle a long gap on my résumé? - any advice?

My résumé shows a gap from a layoff and some health issues. I am not sure how much to explain. What do you say in interviews?

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

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
