Final answer:
It cannot be determined whether going on leave makes Paul feel better or worse, as the information provided does not contain enough context specifically about Paul's situation or reactions.
Step-by-step explanation:
Based on the information provided, it is cannot be determined whether going on leave makes Paul feel better or worse.
The passage speaks to Joaquin's inability to change his situation due to his military commitment and does not directly answer the question about Paul.
Moreover, the information about someone's health potentially improving after some travel does not clearly indicate Paul's feelings regarding leave.
Therefore, without specific information about Paul's circumstances or responses to taking leave, we cannot conclude how it affects him.
