Close to nothing if you live in a multi generational house where people are close by and can take care of each other, thousands per month if you delegate everything to medical practices. I've witnessed both cases, many times
The fact that no money exchanges hands doesn't mean that it costs nothing. The work is still the same. In multigenerational house younger generations pay with their life opportunities for the care.
And yes - I mean I would do that every 6 months.
I’m curious: Do you have any idea what care for such situations costs today?
