I think its a GREAT Idea! Just chuck the whole domestic tranquility mess and go see the world,if not now? When?
Being tied to many anchors for a lifetime is called "stability" Never stray out of the tracks,keep your head down and keep pulling. Once your 65 or so THEN you can relax and have a good time? I think its better to just go,never know what you might find out there.
Some bikes around at times
