As Rigel noted a few days ago, some of the what should be the most rewarding careers are also the most depressing. The top? Personal caregiver.

The amount of sad situations those workers face may make it seem appropriate that depression follows shortly thereafter, and that is really too bad. Those people are the definition of hero, unlike movie stars or professional athletes.

But depression comes out of many fields of work as well, with some ranking much higher than others. Why are engineers and architects less depressed than personal care workers like child care workers and hairdressers?

Simple answer: dealing with objects instead of people produces less depression. Designing a skyscraper may be difficult, but dealing with the cast array of human emotions every day can prove to be just as hard (or harder) for many.
