Unfortunately, true. Countries in the Anglosphere generally don't allow immigration at all past the age of 50 or 55 unless you're married to a citizen or something, so odds are good you aren't even eligible to get in by the time you hit midlife.

And going outside of the Anglosphere requires becoming fluent in a language other than English - and even then it's not so easy to immigrate.

Of course, one can always head to Svalbard - they don't require work visas or residence visas, as per https://www.sysselmesteren.no/en/entry-and-residence/ - but it's pretty cold that close to the North Pole. Plus you'd have to learn Norwegian.
