Everything Sounds the Same When You’re Depressed

This is an interesting study. I've always had trouble understanding speech in anything but a quiet environment. Even the small amount of audio information lost in a phone conversation makes it hard for me to understand what people are saying. However, I don't think I'm depressed any more than the average person (we all have down days sometimes).

So, while depressed people seem to experience this kind of reduced speech comprehension, I wonder what other groups of people experience the same?

According to this, I've been depressed my entire life, ever since I was born.

This is depressing.
