Some examples:
- Being burned mostly to death could give someone a fear/inability to firefight.
- Being trampled mostly to death when a pack revenge happens while hunting might make someone give up on hunting/shooting

- Hauling stuff day in and day out for years might make someone snap and refuse to haul anymore
- your doctor loses one too many patients under his care and decides to retire
