Best place to retire is where you know people, where there is rule of law and reasonable freedoms. When you are old, you can't do as much yourself, so you are much more vulnerable when you get sick, when you don't speak the language, and so on.
UK has healthcare free at point of delivery, is a pretty safe country, and you get a state pension regardless of how broke you are. It's a pretty decent place to retire. Lol at retiring in a 3rd world country, that is even crazier than working in a 3rd world country.
The best places to retire are the same as the best places to live - Western Europe, Japan (if you are Japanese), North America, Australia/New Zealand etc.
