I have a feeling that your market is probably a little less condensed than it is here in the UK.
As for depression, it's a bitch really. Takes seemingly normal people. Rich people. People are very good at hiding it. Men are also really good at killing themselves, far better than women are, apparently. As a guy I think you also take on a lot of social pressure and expectancy. I've also read in the past that it doesn't affect really poor people as much as you might expect, because they are too busy trying to survive to have time to worry.
