Turtle: "Why is this log so wiggly."
Gator: "That rock smells tasty."
Cost of living(rent, utilities, data/wifi, groceries) is $500 USD per month for most countries, $1000 for most others.
Health care and insurance abroad are both pennies on the US dollar for the highest quality of medical care
You usually don't need them; when necessary, visas are almost all entirely online: a fifteen minute e-form and nominal fee offset in your first day by the drastically lower cost of living abroad.
Any job that nets you $500+ a month works. There are almost 2 billion English students globally right now, so native English speakers have lucked into a guaranteed job on or offline.
Some countries and schools require a TEFL certificate or prefer candidates with an associate's degree depending on the position, but if you want to teach English, all you need is to be a fluent English speaker.

I kept expecting the turtle to yell "I'm king of the world!", but I think you're right about "wiggly".
