Is there a relationship between direct happiness and indirect self destruction?

I read that people who work in media and sports news casting have the highest rates of suicide.

I read bar tenders have one of the highest rates of depression and I read farmers and personal trainers and computer technology guys have one of the highest job satisfaction rates.

I think immediate gratification short circuits the spiritual dimensions of life and empties you of all human concerns so that you act and reason like an animal. That might be why people who operate by indulgent lifestyles have higher suicide rates than janitors or garbage collectors or nurses etc…

I do not believe doctors have high suicide rates because the books I read said helping others is good for your mental and physical health.
