My mom FIRE'd at 51 thanks to an inheritance and a renewed fear of her own mortality when my dad passed away that year from a surprise heart attack. Her financials are solid -- she owns her home free and clear, and her investments are making enough money that she travels extensively every year with her BFF and occasionally gifts some out to my sis and me for tax purposes. She has an established will, health care power of attorney and plans to age in place in her community, and fund her healthcare needs.
I would have absolutely zero problems growing up to be my mother, basically. :)
My In-Laws... YIKES.
Father in law was a federal employee/contractor (it's a little unclear) for years. When he basically worked himself out of a job in 2004, he cashed out his entire TSP to buy the house they bought in New Mexico, where he went for his next job. I hope/presume that he has some kind of pension, but he's a contractor now with limited retirement savings, and pushing 65, and grumbling about never retiring, ever. Mother in law has never had a career and works the occasional odd job. She also has a terrible, horrible, deeply chronic spending problem, and isn't exactly in fantastic health.
My husband's only brother is a 35 year old bachelor with a cat who makes pot brownies professionally at a bakery in Colorado. He does not, I should stress, actually eat the pot brownies, which makes him a model bakery employee, but there's not a lot of upward mobility there. He's very happy with his life and roommates and lifestyle, and more power to him for that... but if anything happens to Ma and Pa and they need long-term care or financial assistance it's gonna be on hubby and me to make that happen, most likely from another continent and on next to no notice. I fret about this constantly.
