Depression is good...?!

An interesting article about depression.......

.....with links to the original New York Times article.

This (and the original article) was an interesting read, considering I find myself down more than up these days.

The idea that depression is good because it makes people focus their attention to the critical issues makes sense to me.  But having done neuro research myself, I'd say there really isn't any substantial evidence to make this claim.  At least not from the details they've given here.  It'd be interesting to see the actual paper when it comes out.
