Why you'd want to live there: You'll eat lavishly, every meal of every day. Lima, Peru's capital, rocks a food scene as good as anywhere, with a mix of Chinese, Andean, Japanese, and enduring Incan influences. Put it this way: no country that cultivates 5,000 different varieties of potatoes is anything but deadly serious about food. When you stand up from the table and head out into the country, you'll find a beautiful and incredibly diverse land, dotted with the incredible history of the Inca Trail, Machu Picchu, and Nazca Lines. Plus plenty of Pacific beach towns. Under Pedro Pablo Kuczynski, the mild-mannered centrist (kind of a joker?) who served as president until earlier this year, the relatively stable democratic republic has invited business investment and tourism dollars. Quality dentistry and medical care are bargains, especially in Lima. If you want to go kick the tires for six months, you can; your tourist visa is good for 183 days. And above all, Peruvians seem to genuinely like Americans.
What's the catch: You'll be unemployable if you don't speak Spanish, though there is a need for people who can teach English. Some parts of Lima are not terribly safe. Society at large is more socially conservative and traditionally macho than you might find strictly comfortable, especially if you're not, you know, a man. And despite its status as a world destination, Peru doesn't feel pressure to run on time. Of course, depending on your disposition, this might be a huge plus.
