Should have added "assuming you cannot travel".
Yes, and that is what I intend to do for end of life care However, It is not certain I can just go back for surgery - they changed the rules to prevent non residents doing that - it is pot luck whether you get treated. Some may have to reestablish ourselves in the country to get that treatment. I should be able to stay with family, but being sick and looking for somewhere to live and all the necessary visits to various agencies and all the paperwork won't be easy. Seems B&B in Blackpool is an option.
If you still retain an official presence/property in your own country then it is a "no brainer", but some of us came here with $1,000 and the clothes on our back 25+ years ago.
