Suicide on the increase among middle-aged women

An interesting article that came to me via the American Foundation for Suicide Prevention. It talks about the increase in the rate of suicides and suicide attempts among women over 50. There's no consensus on what exactly is causing this, but there several possibilities are mentioned.
The one I find quite interesting (in a disturbing way) is the one mentioned towards the end saying that women of that age become more aware of their mortality and think it's too late for happiness. I find that very sad.
