A hypothetical question here, but, let's say you're middle aged (40's, married with kids, working). Assuming money is no object - wealthy / comfortable but not at Musk-like levels or anything (again this is hypothetical)...
What plans would you put in place for your old age?
I've witnessed a few family members have depressing / sad last few years in care homes and thinking about if there's a way it can be done better. Without any burden on children though.
