I found an interesting article a couple weeks ago about veterinarians in the work place. It begins with saying how vets have a high level of job satisfaction - above physicians. Then it talks about how also have a very high suicide rate - 4x the general population in the U.S. and 2x other health professions. I've always heard that vets have the highest suicide rate in Europe, but I never knew if that was true or not. The article says the possible reasons are job stress, lethal drug access, and acceptance of euthanasia. Finally, it says that vets are happy people with large animal vets being happier than small animal.
Conclusion: Veterinarians are a happy, suicidal group of people.
