From Peace Corps Wiki
Sometimes, you reach a point in your career where you wonder what would have happened if you had taken a different path. Maybe you enjoy the life you have, but wish you'd had the chance to do something different, something adventuresome, something that matters.
For many people in mid-career, the Peace Corps is the perfect way. Why not get out of the daily grind and do something meaningful? You'll learn a lot about the world and about yourself. You may decide to take a completely different direction with your life when you get back. Or you may return to the same career, but with a renewed sense of purpose and clarity.
