My biggest concern about old age is being able to manage my finances, including avoiding financial abuse by caregivers. I don't have kids or extended family, my partner is much older, I have a lot of longevity AND a lot of dementia on one side of my family, and frankly I'm only in a halfway decent financial position due to prudence, not to being any kind of financial genius. With all of that in mind, it seems to me that at a certain point it is going to make a lot of sense to convert almost everything to a SPIA with an inflation rider. It seems like the best solution for longevity risk and dementia risk, and to protect to a certain extent against abuse.
I would love to get your thoughts on any and all aspects of this, including other ways to get the same benefit without the downsides.
