@TexasBrit - my MIL did that!
Once the oldest two kids were through college and the youngest was well into high school she went out and became a flight attendant. If you can deal with the crazy schedules and the physical labor it seems to be an awesome transition to retirement type of job.
My MIL takes furloughs whenever they are offered which means she gets to keep her benefits (cheap, amazing health insurance) but doesn't work. She and my FIL also get to fly for free so whenever she gets a month off they take trips to crazy places that could never otherwise afford (pro tip - first class to Western Europe is always full but they can usually land first class seats to anywhere in Eastern Europe, Asia or the Middle East quite easily). In the last few years they've taken trips to China, Dubai, Poland, and Turkey/Morocco. She's been doing this almost 20 years now and hopes to be able to keep it up until she hits 70 (she's 65).
