After doing many, many different things in my earlier days (advertising sales, proofreading, directing a non-profit organization, etc), I finally settled into being an executive assistant which is where I found my niche. Believe me, that is one field that age and experience are appreciated. My former bosses still call me a couple times a year asking if I'd be interested in coming back to work on a part-time or temporary business. One said it's because I know whose ass to kiss, whose ass to kick and where the skeletons are buried. I'm not at all interested, but it's an ego boost being asked.
