Pre-temple fall, Baze would lose himself to translating old texts, or sweeping the courtyard, or any number of chores that needed done around the temple. He didn't really do well being idle.

Post-temple fall, he didn't take a lot of recovery time from injuries and illnesses, much less vacation time. He wouldn't know what to do with himself. He'd probably try cooking something.

Now, all he has is idle time. He brews beer and spars with Chirrut and reads and reads and reads.
