Just out of interest does anyone have any thoughts on why there seems to be so much depression around these days?

Is it our lifestyles? Do we put so much pressure on ourselves to be super-human and perfect, as we rush around trying to live up to false expectations and then falter under the strain?

Or, is it just the same as it ever was but is no longer being hidden under the carpet with people no longer prepared to accept it as one-of-those-things ?
