When we evaluated this we decided that what John enjoys isn't relevant for deciding what you should do, especially if he enjoys doing something silly or dangerous. Think about this for a minute: we didn't reject the claim that John enjoys smoking - we decided that it was irrelevant for deciding what you should do. What we actually rejected was an unstated assumption: you should do whatever John enjoys doing.

That assumption can be brought into the open using an Analysis map:

This map is more precise because it breaks down the reason into multiple claims, which are called 'premises'.  These claims aren't two separate reasons - they work together as part of a single reason.
