A young person just starting out, a thirty-something adventurer, or an older couple whose kids are on their own can trade their skills and talents directly for basic living expenses – shelter and food the primaries among those necessities. While at the same time “seeing the world” and doing some good. There are many missions, NGO projects and other affiliated concerns who are always in need of warm bodies to do the work they’re dedicated to providing. All over the world, and all over the US of A. You’ll never get rich vaccinating children or passing out food or building schools, digging wells, teaching, installing energy systems, etc. in the Third World. Heck, many such jobs pay nothing at all. But you’ll usually get a place to sleep, food to eat and experiences enough to fill storytelling voids forever!
