Imagine for a moment that among humans some people can fly. Government staff come and tell you that you can take a course that will teach you how. This sounds great, and one hears of emotional accounts of what it is like to soar in the sky. But you have no personal experience of what flying feels like. To learn it you must go for six to nine months daily to school. You do exercises like flapping your arms but you never really take off. And you do not often need to fly anywhere. Whenever you do, you can either take the plane or send a relative who can fly to do what is needed. So, is the benefit worth the effort?
