As always, it depends on one's point of view. There are some that regard retirees here as failures.
OTOH, I made the move because I felt stifled in my home country. How many men have the guts in their 60's to learn a new language, immerse themselves in a foreign culture, and walk away from everything that is familiar and comfortable?
I once worked with a guy whose ambitions were to marry his sweetheart, have kids, buy a house in his home suburb, and barrack for his football team for the rest of his life, attending every match.
He ridiculed me for wanting to travel. One of his ambitions was achieved when his wife ( good Catholics ) presented him with twins.
I didn't hear any more about him, maybe he is content. A pretty dull life IMO.
