"Pulling up Sticks for good" meant just that for me.
After the death of my dad I was the only one left living in the UK from our known family.
All but one of my childhood pals had also left UK

I pulled up sticks and left for the only place where I had 'family' to look out for me.
Didn't need to burn any bridges as there were none to burn.

I've taken advice from others and kept my UK bank account and debit card.
I've taken up a UK mailing address at an organisation that specialises in managing mail.
Everything is done online including any scanning, shredding or forwarding.

Concerning medical care and costs here in the Philippines well we all know it's not free.
Major requirements will be eye-wateringly expensive.
In my experience medical care here is variable depending where you live. It's a factor for many when finalising just where to live. For us we are within 15 minutes of 4 great hospitals including Davao Docs which is said to be world class.
(With a matching price tag too)

I've known only one person return for medical reasons. He was on dialysis due to renal failure but sadly didn't make it long enough to secure the needed transplant donor.
I've know a couple of people whose prognosis wasn't at all good and who decided to remain here and enjoy the best love and care anyone would want. Sadly both passed away recently.

Most of those folks who spent large amounts of cash on medical needs did so for their extended family or for their wives who didn't want to leave.
There was one Brit I got to know who spent over P5 mill on cancer treatment for his aged mother in law over a 4 year period. When she died they were virtually penniless and had to sell up the house they'd built and downsize in order to manage. Last time I spoke with him his health wasn't so good and he told me he had given up his medication as he couldn't afford the P9000 per month to keep up. He asked me not to say anything as he hadn't told his wife he'd stopped.
He said they had no intention of returning to UK since he felt that despite everything he was happier here and life was still good.

Personally I have no intention of returning.
Mind you if either me or my wife were told we needed some expensive treatment to stay alive and we thought we could only get that free on the NHS, who knows in all honesty just which way we'd actually jump. It all depends on the specific circumstances and impacts to everyone concerned.
Personal choices are just those and thankfully right now we do have choices. Maybe next year those choices are much less. Maybe in 2 years or 5 years we have no choice. C'est la vie.

My dad had poor health during his final years and got fed up with all the medications, side-effects and tests etc. He admitted to me often that he'd had enough of this world, he was tired and wanted it to end. Most days his pain was just too much.
I would never want to end like that.

I'm happier than I thought I could be. I'm content and lucky to be actually living my dream.

I hope I never have to prioritise whatever funds I have between me, my wife or another family member.
Sometimes it's better not to analyse that too much and focus on the day we have now and cross those other bridges when we need to.
Just my thinking
