Not enough information.
If you are looking into the future, the world is changing too fast. It is changing beyond recognition every decade--literally--and the pace is accelerating.
Do not expect to go to one place and stay for the rest of your life--even in the USA--in your working life or in retirement/financial independence phase.
Be aware that some places you may want to go to will not let you stay (e.g., Canada, New Zealand, most of Europe, etc etc).
Like MichaelB, Kramer, HaHa and others here, I have been many places around the world. All that said, first choice for my wife and me is still the USA--if we can afford it!! Survival will be excitement enough. We don't need discos in Torremolinos or climbing the Himalayas. You might.
I have a list of places where I would like to spend extended periods of time after I hang up the slide rule, which is in a couple of years. Having good genes, we could last another 30 years.
For us, Mexico is the second choice (only a few locations and with reservations). The next group includes Belize and maybe four South American countries. The third group includes Turkish Cyprus and maybe Portugal or Spain. Mexico and Belize have the advantage of being close to home.
If we had the money, we would go back to Denmark in a flash.
You can have Asia, India, Africa and Newark. Been there.
