During a person's working years, they probably want to work and live in a big city where there are many companies and employers, many career opportunities, many great restaurants and entertainment facilities, etc.
But after a person retires, many retirees want to live in a country that has a warm climate, in a smaller city or town, and a place that offers good medical services.
I'm retired, so I would love to live on a tropical island, surrounded by a beautiful ocean, with good restaurants (because I'm the worst cook in the world), and a good Internet Service Provider so I can stay in contact with my friends and students at italki.
Any suggestions? :)
Good question Alberto
